Philadelphus microphyllus is a species of mock-orange known by the common name littleleaf mock-orange. It is native to northern Mexico and the southwestern quadrant of the United States as far north as Wyoming, where it grows in scrub and brush habitat in foothills and mountains, often in very rocky areas, sometimes anchoring itself in rock cracks and crevices. It is a highly variable plant with many subspecies. In general it is a rounded, spreading shrub reaching a maximum height around 2 meters. Young branches are coated in stiff hairs, and older branches have reddish, yellowish, or gray shredding bark. The pointed oval or lance-shaped leaves are up to 2.5 centimeters long, green, and sometimes hairy. They are oppositely arranged and deciduous. The flower cluster is a solitary flower or cluster of two or three. The fragrant flower has four or five white or cream petals and a cluster of many stout stamens. The fruit is a hard capsule containing many seeds. This flowering shrub is propagated and used as a drought-tolerant ornamental plant in its native range.

Physocarpus capitatus (Pacific Ninebark) is a species in the Rosaceae (Rose) family native to western North America from southern Alaska east to Montana and Utah, and south to central California. It is found in the Coast Ranges and the Sierras. It is a dense deciduous shrub growing to 1 to 2.5 meters tall. The name comes from the appearance of the bark, which is flaky, peeling away in many layers. The shrub has distinctive maple-like lobed leaves 3-14 centimeter long and broad, and ball-like clusters of small white flowers with five petals and numerous red-tipped stamens. The unique fruit is an inflated glossy red pod which turns dry and brown and then splits open to release seeds. It is most often found near streams in association with wetland-riparian vegetation. Near the coast and at higher elevations it can take full sun. At lower elevation inland locations it benefits from part shade and moisture. It's leaves change color in fall before dropping. The extensive root system is useful for retaining soil on slopes. It makes a very attractive shrub or small tree for central to northern California gardens.

Grows best in loamy, medium draining soil. Selected for the garden.

The Sitka Spruce (Picea sitchensis) is a large coniferous evergreen tree growing to 50-70 meter tall, exceptionally to 100 meter tall, and with a trunk diameter of up to 5 meter, exceptionally to 6-7 meter diameter. Native to the northwest coast of North America, primarily Humboldt and Del Norte Counties in California, it is by far the largest species of spruce, and the third tallest conifer species in the world (after Coast Redwood and Coast Douglas-fir). Also, the fourth largest conifer (behind Giant Sequia, Coast and Western Red Cedar). It acquires its name from the community of Sitka, Alaska. The bark is thin and scaly, flaking off in small circular plates 5-20 centimeter across. The crown is broad conic in young trees, becoming cylindric in older trees; old trees may have no branches in the lowest 30-40 meter. The shoots are very pale buff-brown, almost white, and smooth (hairless) but with prominent pulvini. The leaves are stiff, sharp and needle-like, 15-25 millimeter long, flattened in cross-section, dark waxy pale blue-green above with two or three thin lines of stomata, and blue-white below with two dense bands of stomata.

Pinus contorta is a common tree in western North America with the bulk of its population to the north and east of California. Within California it is found primarily in the Sierras, with scattered populations in other mountains. There are three recognized subspecies which can vary greatly in appearance. In the Sierras ssp. Murrayana can be very tall with a straight trunk, consistent with the common name Lodgepole Pine. It is found at elevations from 1,500 ft. to 12,000 ft. Near the coast ssp. contorta can be shrub height with twisted trunk and branches and known as Beach Pine. It is found from sea level to about 2,000 ft. Ssp. bolanderi is a rare species from the coast of Mendocino County northward to Oregon.

Pinus contorta is a moderately important timber wood but not often used in landscaping. The needles are held in bundles of two. The cones of may be of either the closed or open type and remain on the tree for many years. The bark is relatively thin and susceptible to fire.

Shore Pine (Pinus contorta ssp. contorta) is a native tree that grows in Central and Northern California, primarily in the North Coast region. It tends to grow at elevations from 0-11500 feet.

The Coulter Pine or Big-cone Pine (Pinus coulteri) is a native of the coastal mountains of southern California (United States) and northern Baja California (Mexico). Isolated groves are found as far north as the San Francisco Bay Area in Mt. Diablo State Park and Black Diamond Mines Regional Preserve. The species is named after Thomas Coulter, an Irish botanist and physician. The size ranges from 10-24 meter (30-80 feet) tall, and a trunk diameter up to 1 meter (3 feet). The trunk is vertical and branches horizontal to upcurved. The leaves are needle-like, in bundles of three, waxy pale gray-green, 15-30 centimeter (6-12 inches) long and stout, 2 millimeter (0.01 inch) thick. The outstanding characteristic of this tree is the large, spiny cones which are 20-40 centimeter (8-16 inches) long, and weigh 2-5 kg (4-10 lbs) when fresh. Coulter Pines produce the largest cones of any pine tree species (people are actually advised to wear hardhats when working in Coulter Pine groves), although the slender cones of the sugar pine are longer. The large size of the cones has earned them the nickname "widowmakers" among locals. The wood is weak and soft, so that the species is little used other than for firewood. It is also occasionally planted as an ornamental tree in parks and large gardens.

Jeffrey Pine (Pinus jeffreyi), named in honor of its documenter John Jeffrey, is a North American pine related to Ponderosa Pine. It occurs from southwest Oregon south through much of California, including the Sierras, Coast Ranges, Transverse Range and Peninsular Range, to northern Baja California, Mexico. It is a high altitude species; in the north of its range, it grows widely at 1,500 to 2,100 meter (4,900 to 6,900 feet) altitude, and at 1,800 to 2,900 meter (5,900 to 9,500 feet) in the south of its range. The Jeffrey Pine is a large tree, reaching 25 to 40 meter (82 to 131 feet) tall, rarely up to 53 meter (174 feet) tall, though smaller when growing at or near tree line. The leaves are needle-like, in bundles of three, stout, waxy pale gray-green, 12 to 23 centimeter (4.7 to 9.1 inches) long. The cones are 12 to 24 centimeter (4.7 to 9.4 inches) long, dark purple when immature, ripening pale brown, with thinly woody scales bearing a short, sharp inward-pointing barb. The seeds are 10 to 12 millimeter (0.39 to 0.47 inches) long, with a large (15 to 25 millimeter (0.59 to 0.98 inches)) wing. In the Sierras and Peninsular Range it grows primarily on granite, but in the Coast Ranges it is found largely on Serpentine soils. The bark has a distinctive fragrance described as reminiscent of vanilla, lemon, pineapple, violets, apple, or butterscotch. It is tolerant of drought, cold and heat.

Pinus lambertiana (commonly known as the sugar pine or sugar cone pine) is the tallest and most massive pine tree, and has the longest cones of any conifer. It is native to the mountains of the Pacific coast of North America, from Oregon through California to Baja California. The sugar pine occurs in the mountains of Oregon and California in the western United States, and Baja California in northwestern Mexico; specifically the Cascade Range, Sierra Nevada, Coast Ranges, and Sierra San Pedro Martir. The sugar pine is the largest species of pine, commonly growing to 40-60 meters (130-200 ft) tall, exceptionally up to 82 m (269 ft) tall, with a trunk diameter of 1. 5-2. 5 m (4. 9-8. 2 ft), exceptionally 3. 5 m (11 ft). Pinus lambertiana is a member of the white pine group, Pinus subgenus Strobus, and like all members of that group, the leaves ('needles') are in bundles (fascicles) of five, with a deciduous sheath. They are 6-11 cm (2. 4-4. 3 in)ch) long. Sugar pine is notable for having the longest cones of any conifer, mostly 25-50 cm (9. 8-19. 7 in) long, exceptionally up to 66 cm (26 in) long (although the cones of the Coulter pine are more massive). The seeds are 10-12 mm (0. 39-0. 47 in) long, with a 2-3 cm (0. 79-1. 18 in) long wing that aids wind dispersal. The seeds of the sugar pine are also a type of pine nut and are edible.

The Single-leaf Pinyon (Pinus monophylla) is a pine in the pinyon pine group, native to the United States and northwest Baja, Mexico. Within California it is found in the Sierras, the Transverse Range, and Peninsular Range. It occurs at moderate altitudes from 1200-2300 meter, rarely as low as 950 meter and as high as 2900 meter, in the most arid areas occupied by any pine in California. It is widespread and often abundant in this region, forming extensive open woodlands, often mixed with junipers. It is a small to medium size tree, reaching 10-20 meter tall and with a trunk diameter of up to 80 centimeter, rarely more. However, it is very slow growing, reaching only 3 ft. in seven years.The bark is irregularly furrowed and scaly. It is the world's only 1-needled pine; the leaves ('needles') are usually single (though trees with needles in pairs are found occasionally), stout, 4-6 centimeter long, and grey-green to strongly waxy pale blue-green, with stomata over the whole needle surface (and on both inner and outer surfaces of paired needles). The cones are acute-globose, the largest of the true pinyons, 4.5-8 centimeter long and broad when closed, green at first, ripening yellow-buff when 18-20 months old, with only a small number of very thick scales, typically 8-20 fertile scales. The cones open to 6-9 centimeter broad when mature, holding the seeds on the scales after opening. The seeds are 11-16 millimeter long, with a thin shell, a white endosperm, and a vestigial 1-2 millimeter wing; they are dispersed by the Pinyon Jay, which plucks the seeds out of the open cones. The jay, which uses the seeds as a food resource, stores many of the seeds for later use by burying them. Some of these stored seeds are not used and are able to grow into new trees. Indeed, Pinyon seeds will rarely germinate in the wild unless they are cached by jays or other animals. The seeds (pine nuts) are also harvested and eaten by people.

The Bishop Pine (Pinus muricata) is a pine with a very restricted range: mostly California, USA, including some offshore islands, and a few locations in Baja California, Mexico, and always on or near the coast, from Trinidad Head in Humboldt County, California south to San Vicente in Baja California. The mature trees grow to a height of 15-25 meter, rarely up to 34 meter, with a trunk diameter of up to 1.2 meter. The species is often smaller, stunted and twisted in coastal exposures. It is drought-tolerant and grows on dry, rocky soil. P. muricata has been used in plantations with resultant growth rates higher than in the wild, but with adverse impacts to biodiversity. The common name Bishop Pine resulted from the tree having been first identified near the Mission of San Luis Obispo. This tree has a large number of common names and other prior scientific names, due primarily to numerous variant forms. Other English names that have occasionally been used are: Obispo Pine, Santa Cruz Pine, Dwarf Marine Pine, and Pricklecone Pine.

Pinus ponderosa, commonly known as the Ponderosa Pine, Bull Pine, Blackjack Pine, or Western Yellow Pine, is a widespread and variable pine native to western North America. It was first described by David Douglas in 1826, from eastern Washington near present-day Spokane. It is a dominant tree in the Kuchler plant association Ponderosa shrub forest. Like most western pines, the ponderosa is associated with mountainous topography. It is found on the Black Hills and on foothills and mid-height peaks of the northern, central and southern Rocky Mountains as well as the Cascades and Sierra Nevada. Modern forestry research identifies four different taxa of Ponderosa Pine, with differing botanical characters and adapted to different climatic conditions. These have been termed "geographic races" in forestry literature, while some botanists historically treated them as distinct species. In modern botanical usage, they best match the rank of subspecies, but not all of the relevant botanical combinations have been formally published.

Foothill Pine (Pinus sabiniana), also known as gray or ghost pine, is a slow-growing and moderately long-lived tree native to California. It grows at elevations up to 4,500 feet and has distinct, long, drooping, silvery-green foliage. The yellow flowers bloom in early spring, and the tree bears sweet edible seeds. This pine is quite resilient, thriving in areas with poor soils and dry conditions.

Foothill Pine grows in an upright form to a height of up to 80 feet, but with regular irrigation, it can reach 40-60 feet in landscaping applications. Its feathery, lacey canopy allows plenty of light to filter through, making it an excellent choice for planting understory plants beneath it without much interference. This tree is perfect for dry, challenging areas and provides a soft, dappled shade.

The Torrey pine (Pinus torreyana) is the rarest pine in the U.S., found only along San Diego's coast and on two Channel Islands. This endangered tree grows 26–56 feet tall with long, gray-green needles in clusters of five and large, edible pine nuts in stout cones. It thrives in dry, sandy soils and coastal fog, often developing twisted, sculptural forms from wind exposure.

The pine nuts are a valuable food source for birds, small mammals, and other wildlife. Its dense canopy also provides nesting and shelter for birds.

Historically limited to about 100 trees in the early 20th century, conservation efforts have helped the wild population recover to around 3,000. Torrey pines are now planted in drought-tolerant landscapes and protected by local ordinances near their native range. In gardens with richer soil and more water, they can grow over 100 feet tall.

Plantago erecta is a small, unassuming annual herb with needle-like leaves and translucent flowers clustered on a stalk. It grows in sandy, clay, or serpentine soils, on grassy slopes and flats or open woodland, from California to Oregon. It is known variously as California Plantain, Foothill Plantain, Dot-seed Plantain, English Plantain, and Dwarf Plantain. P. erecta is a primary host plant for the Bay Checkerspot Butterfly.

Plantago subnuda is a species of plantain known by the common name tall coastal plantain. It is native to western North America from the west coast of the United States to west-central Mexico, where it grows in wet and moist habitat types, often in coastal areas, such as marshland. It is a perennial herb producing few oval leaves around a thick caudex. The broad smooth-edged or slightly toothed leaves may be up to 40 centimeters long. The stemlike flower clusters grow erect to a maximum height near half a meter. Atop the peduncle of the flower cluster is a dense cylindrical spike of many tiny flowers. Each flower has a corolla of ephemeral petals about 3 millimeters long.

The Western Sycamore (Platanus racemosa), a species of plane tree native to California, is a tall, distinctive tree that stands out in any landscape. This tree is known for its bark, which is mottled in shades of pale tan, gray, and white. The bark peels as it ages. It has twisting branches and large leaves which turn orange-yellow in the fall. It produces seed balls after blooming. It's an important host plant for the Western Tiger Swallowtail butterfly.

Naturally found in moist areas near rivers and streams, this tree requires a significant amount of water to thrive. When not planted near a water source, it needs regular irrigation. The Western Sycamore tolerates different soil types and does best in full sun. It can grow up to 100 feet tall and 50 feet wide, so be sure to give new trees a large planting area.

Pluchea odorata is a species of flowering plant in the aster family, Asteraceae, that is native to the United States, Mexico, Central America, the Caribbean, and northern South America. Common names include Sweetscent, Salt Marsh Fleabane, and Shrubby Camphorweed. It inhabits wetlands and other coastal habitats and moist inland areas, often in saline substrates. It is an introduced species and a noxious weed in Hawaii. It is an annual or perennial herb growing erect to a maximum height over one meter. It is hairy, coated in rough trichomes (hairs), and strongly aromatic. The toothed oval leaves are up to 12 centimeter (4.7 inches) long and alternately arranged on the stiff stems. The flower cluster is a large cluster of many flower heads. Each head is less than 1 centimeter (0.39 inches) long and filled with bright pinkish-purple or magenta flowers. The fruit is a tiny achene tipped with a bristly pappus.

Pluchea sericea, commonly called Arrowweed, is a rhizomatous evergreen shrub of riparian areas in the lower Sonoran Desert and surrounding areas. It is common in the lower Colorado River valley of California, Nevada and Arizona, as far east as Texas, and in northern Mexico where it often forms dense impenetrable thickets. It was once used medicinally by Native Americans as an antidiarrheal and eyewash. Other traditional uses include thatching, arrowmaking and food, especially the edible root.

Poa secunda (variously known by the common names of Sandberg bluegrass, alkali bluegrass, big bluegrass, Canby's bluegrass, Nevada bluegrass, one-sided bluegrass, Pacific bluegrass, pine blugrass, slender bluegrass, wild bluegrass, and curly bluegrass. ) is a widespread species of grass native to North and South America. It is highly resistant to drought conditions, and provides excellent fodder; and has also been used in controlling soil erosion, and as revegetator, often after forest fires. Cultivars include 'Canbar', 'Service', 'Sherman', and 'Supernova'. Historically, indigenous Americans, such as the Gosiute of Utah, have used P. secunda for food. It was originally described botanically in 1830 by Jan Svatopluk Presl, from a holotype collected from Chile by Thaddäus Haenke in 1790.

Tolerates almost any soil type. Prefers shade in coastal sites, and shade in inland sites. Selected for the garden.

Leathery Polypody (Polypodium scouleri) is a native fern that grows along the coast primarily in northern and central California, from Santa Barbara County northward, and on Santa Cruz Island. It tends to grow in fog drip or saltspray zones, at elevations from sea level to 2,000 feet. It is quite often seen growing on trees or fallen logs and spreads slowly by rhizomes. It is an attractive fern for shaded areas.

Western sword fern (Polystichum munitum) is a large evergreen fern with dark green fronds that grow in a tight clump, spreading out radially from a round base. It grows up to 6 feet tall and 5 feet wide and is moderate to fast growing. Individual fronds live for 1.5-2.5 years and remain attached to the base after withering.

It is excellent as an ornamental groundcover for shade. Plant in partial to full shade and give moderate to regular water. It prefers well-draining, rocky, acidic soil but can tolerate clay.

This plant attracts butterflies and hosts a likely total of 3 species of butterfly and moth. It is deer and rabbit resistant.

Fremont cottonwood (Populus fremontii) is a fast-growing native shade tree found in alluvial bottomlands and along streamsides at elevations from 0 to 6,500 feet. It thrives in moist soils with plenty of sunlight and is known for its striking, heart-shaped leaves that shimmer in the wind.

This tree is tough and easy to grow, reaching up to 100 feet tall and 35 feet wide when well-watered. It can grow 10–20 feet in a single year, making it ideal for large spaces but unsuitable for small gardens. Due to its invasive roots, it should not be planted near lawns or structures.

Often, only male trees are sold to avoid the "cotton" produced by female trees. Fremont cottonwood is ecologically important, providing habitat and food for birds and butterflies.

Grows best in loamy, medium draining soil. Selection (male) for the garden.

Populus tremuloides is a deciduous tree native to cooler areas of North America. The species is referred to as Quaking Aspen, Trembling Aspen, and Quakies, names deriving from its leaves which flutter in even a slight breeze. The tree can become tall, up to 25 meters, but is more often half that height, with smooth pale bark scarred with black. The glossy green leaves, dull beneath, become golden to yellow, rarely red, in Autumn. The species rarely flowers, often propagating through its roots to form large clonal groves. The quaking or trembling of the leaves is due to its flattened petioles. The specific epithet, tremuloides, is given for this trembling characteristic. Other species of Populus have petioles flattened partially along their length, while the Quaking Aspen's are flattened from side to side along the entire length of the petiole. This quaking of the leaves produces a soft sound that many consider a hallmark of the Quaking Aspen. It can be found in many parts of North America. In California it is most common in the Sierras and other high elevation mountains. Nurseries usually sell only male plants because female plants can produce large amounts of cottony seeds. Unless you have acreage, use caution in planting this tree because it will send out suckers long distances to quickly form a dense grove that will fill in any moist area. There are usually few understory plants in Quaking Aspen groves.

Potentilla gracilis, known as Slender Cinquefoil, or Graceful Cinquefoil is a species of cinquefoil. Named varieties are:

Prosartes hookeri is a North American species of flowering plants in the lily family known by the common names drops of gold and Hooker's fairy bells.
It is native to western North America from Alberta and British Columbia to California to Montana, where it usually grows in shady, damp areas, such as forest understory. Additional populations have been found in the Black Hills of Wyoming and South Dakota as well as in the Porcupine Mountains in Michigan. A typical west coast habitat is in forest floors of California oak woodlands, where common understory flora associates may include Coastal woodfern, Dryopteris arguta; Maidenhair fern, Adiantum jordanii and False Solomon's seal, Maianthemum racemosum.
It is an erect, few-branched perennial herb growing up to a meter tall from a rhizome. Its narrow, fuzzy stems bear wide, oval-shaped, pointed leaves up to 15 centimeters long and hairless to hairy, often with hairs along the edges and on the veins underneath. The inflorescence at the tips of branches produce one to three drooping, hanging flowers which may be hidden in the cover of the large leaves. The flower is bell-shaped with six white to green veiny tepals and six protruding stamens with large anthers. The fruit is an orange to bright red berry just under a centimeter wide.

Prunella vulgaris, known as common selfheal, heal-all, heart-of-the-earth or h kh tho in Vietnamese, is a medicinal plant in the genus Prunella. It grows from 1 to 2 feet high, with creeping, self-rooting, tough, square, reddish stems branching at leaf axis. The leaves are lance shaped, serrated and reddish at tip, about an inch long and 1/2 inch broad, grow on short stalks in opposite pairs down the square stem. The flowers grow from a clublike, somewhat square, whirled cluster, immediately below this club are a pair of stalkless leaves standing out on either side like a collar. Flowers are two lipped and tubular, the top lip is a purple hood, and the bottom lip is often white, it has three lobes with the middle lobe being larger and fringed upwardly. Flowers bloom at different times depending on climate and other conditions; Mostly from June to August. For medicinal purposes, the whole plant is gathered when the flowers bloom, and dried. The leaves and small flowers of heal-all are edible. Heal-all is a perennial herb found throughout Europe, Asia, Japan and the United States of America, as well as most temperate climates. Its origin seems to be European, though it has been documented in other countries since before any history of travel. In the United Kingdom it is abundant throughout Wales, Scotland, Northern Ireland and England. In the Republic of Ireland it is currently abundant in the west in counties Galway and Clare, the south-west in Kerry, the south coast and is also found around the central basin of Ireland. It is often found growing in waste ground, grassland, woodland edges, usually on basic and neutral soils. It is grown in any damp soil in full sun or in light shade. Seeds are sown in very early spring in a flat outdoor area.

Hybrid of Prunus ilicifolia ssp. ilicifolia (Hollyleaf Cherry) and P. ilicifolia ssp. lyonii (Catalina Cherry). Tolerates almost any soil type. Prefers sun in coastal sites, and sun or part shade in inland sites. Selected for use in the garden.

Oregon cherry or Bitter cherry (Prunus emarginata) is a species of Prunus native to western North America, from British Columbia south to California, and east to western Wyoming and Arizona. It is often found in recently disturbed areas, open woods, on nutrient-rich soil. It is a deciduous shrub or small tree growing to 1-15 meter tall with a slender oval trunk with smooth gray to reddish-brown bark with horizontal lenticels. The leaves are 2-8 centimeter long, thin, oval-shaped, and yellowish-green with unevenly-sized teeth on either side. The flowers are small, 10-15 millimeter diameter, with five white petals and numerous hairlike stamens; they are almond-scented, and produced in clusters in spring, and are pollinated by insects. The fruit is a juicy red or purple cherry 7-14 millimeter diameter, which, as the plant's English name suggests, are bitter. As well as reproducing by seed, it also sends out underground stems which then sprout above the surface to create a thicket.

Prunus fremontii is a North American species of plants in the rose family, known by the common name desert apricot. It takes its scientific name from John C. Frémont. It is found in northern and western Baja California especially, mostly Pacific and western, and the adjacent area of southern California. It also occurs in northern Baja California Sur. Prunus fremontii is a deciduous shrub or small tree reaching up to five meters (16 2/3 feet) in height. Flowers are white or pink, blooming about the same time as the leaves unfurl in the Spring. Fruits are yellow and egg-shaped.

Hollyleaf cherry or Evergreen cherry is a species in the Rosaceae (Rose) family that is native to coastal California and northern Baja California. It is an evergreen shrub or small tree up to 15 meters tall, with dense, sclerophyllous foliage. The leaves are 1.6-12 centimeter long with a 4-25 millimeter petiole and spiny margins, somewhat resembling those of the holly, hence its English name; they are dark green when mature and generally shiny on top, and have a smell resembling almonds when crushed. The flowers are small (1-5 millimeters), white, produced on racemes in the spring. The fruit is a cherry 12-25 millimeter diameter, edible and sweet, but contains little flesh surrounding the smooth seed. Great for birds.

There are two recognized subspecies; ssp. lyonii (commonly known as Catalina Island Cherry) is native to the Channel Islands. It was formerly considered a separte species, and it is very similar in appearance and genetics to other P. ilicifolia. They hybridize readily, and many plants sold in nurseries may be unintentional hybrids.

Hollyleaf Cherry (Prunus ilicifolia ssp. ilicifolia) is a native evergreen tree or shrub in the Rose family that grows in the coastal and inland valleys strip of northern, central, and southern California. It tends to grow on slopes or in valleys, at elevations from 0-5200 feet. It grows in chaparral, coastal sage scrub, and southern oak woodland habitats and can vary greatly in size depending on conditions. In dry, rocky or shallow soils it will be bush-like from 5 to 15 ft. In richer soils with more moisture it will attain large shrub or small tree size, up to 30-40 ft.
The leaves are holly-like and evergreen. The flowers are small and white; the fruit is a one inch red to dark purple drupe that is popular with wildlife. The closely related subspecies Prunus ilicifolia ssp. lyonii (Catalina Cherry) is endemic to the Channel Islands, but in appearance and behavior the two can be difficult to distinguish as they hybridize readily.

Catalina cherry (Prunus ilicifolia ssp. lyonii) is a lovely evergreen shrub with shiny soft leaves and dark cherry colored fruit.  In late spring, striking white flowers appear. Older trees may resemble coast live oak.

As a native plant, it grows in chaparral woodland, primarily in the Channel Islands region.

The edible fruits are favored by birds and other wildlife. 

Catalina cherry can be planted as a hedge because its dense vegetation creates a good screen. It is fairly easy to grow and will tolerate garden conditions, with summer watering once or twice a month. It is fast growing once established and moderately long-lived.  Fallen fruits may stain concrete paving, if any is nearby. 

Choke Cherry (Prunus virginiana) is a species in the Rosaceae (Rose) family, in the Bird Cherry (Padus) subgenus. It is native to North America where it is found almost throughout the continent except for the deep south and the far north. The plant is widespread in California, particularly in the mountains. It is a suckering shrub or small tree growing to 5 meter tall. The leaves are oval, 3-10 centimeter long, with a coarsely serrated margin. It is deciduous, and the leaves provide some fall color. The flowers are produced in racemes of 15-30 inches late spring (well after leaf emergence). The fruits are about 1 centimeter diameter, range in color from bright red to black. Although they are said to be edible, they contain small amounts of cyanide, especially when unripe. The very ripe berries are dark in color, less astringent, and contain less cyanide. Despite the potential toxicity, the fruits were valued by many Native people.

Western Chokecherry (Prunus virginiana var. demissa) is a native tree or shrub that grows in northern, southern and central California. It is fast growing and short-lived. It grows in an upright form to a height of 20 feet, with active growth during the spring and summer. Flowers are white and striking, and bloom in the spring. Leaves are medium green and deciduous. It tends to grow in rocky slopes, at elevations from 0-8200 feet.

California Cudweed (Pseudognaphalium californicum) is a species of flowering plant in the Asteraceae (Sunflower) family. It is native to the west coast of North America from Washington to Baja California, where it is a member of the flora of many habitats, including chaparral. In California it is most often found near the coast from Sonoma County southward and in the Sierra foothills.

This is an annual or biennial herb with branching stems. Its green herbage is hairy, sticky and scented. The flower head is a wide cluster of flowers, each enveloped in ringed rows of bright white. The flowers are very long lasting when dried and are used in flower arrangements.

Classification is disputed between the genera Pseudognaphalium and Gnaphalium, but it is presently classified as Pseudognaphlium. Also, some sources refer to this plant as Pearly Everlasting, but that's actually the common name of a different species (Anaphlis margaritacea). California Cudweed would work best in an informal garden or wildscape. It re-seeds prolifically, so be prepared to pull seedlings from areas where it is not wanted.

Pseudognaphalium canescens (syn. Gnaphalium canescens) is a species of flowering plant in the Asteraceae (Sunflower) family known by the common name Wright's Cudweed. It is native to western North America from western Canada to northern Mexico. It can be found in many habitats, from mountains to plateau to coastline. The many-branched stem is erect to a maximum height of around a meter. It is gray-green and woolly with many narrow leaves. Atop the stem branches are flower clusters of several pointed oval-shaped pale yellowish, cream, or white flower heads. Each woolly head is a few millimeters across and contains many tiny disc florets. This plant is seldom seen in gardens but is useful for restoration projects.

White Everlasting (Gnaphalium canescens ssp. microcephalum) is a native perennial herb in the Asteraceae (Sunflower) family that grows primarily in southern California, along the central coast, and in the Sierras. It tends to grow at elevations from sea level to 6,500 feet. Like other members of this genus, the flowers are very long-lasting when dried and are used in flower arrangements. It is the larval host plant for the American lady butterfly. Fuzzy greenish-white leaves and stems sometimes visited by Woolcarder Bees, who harvest the fuzz to build their nests. Flowers very long lasting and good in dried flower arrangements. Pioneer species along with native grasses and lotus (Acmispon) species.

Douglas Fir or Douglas-fir, Pseudotsuga menziesii, is an evergreen conifer native to the coastal regions of western North America, from central California north through Oregon and Washington to British Columbia, Canada. In California, it is found in the Klamath Mountains and the Cascade Range, the California Coast Ranges as far south as the Santa Lucia Mountains in Monterey County, and the Sierra Nevada as far south as the Huntington Lake region in Fresno County.

In California the Douglas Fir and its variety named Coast Douglas Fir (Pseudotsuga menziesii var. menziesii) occur from near sea level along the coast to 5,900 feet (1800 m) in the Sierra Nevada. Eastward they are replaced by its variety named Rocky Mountain Douglas Fir (Pseudotsuga menziesii var. glauca). Its variety named Mexican Douglas Fir (Pseudotsuga menziesii var. lindleyana) is endemic to central and northern montane Mexico.

Douglas Firs commonly live more than 500 years and occasionally more than 1,000 years. The species name, menziesii, honors Archibald Menzies, the first European botanist to document it (1791). The common name honors botanist David Douglas, who introduced it into cultivation (1827). Douglas Firs are commercially important for lumber.

Due to their robust mature size Douglas Fir trees are not frequently planted in small to mid-size residential gardens. Since they can get exceptionally large they need to be provided with plenty of space to grow above and below ground.
Douglas Firs are the second-tallest conifer species in the world after Coast Redwoods (Sequoia sempervirens). Trees 200-250 feet (60-75 meters) in height and trunks 5-6.6 feet (1.5-2 m) in diameter are common in old growth forests. Maximum heights of 330-390 feet (100-120 m) and trunk diameters of 15-20 feet (4.5-6 m) were historically documented. The "Doerner Fir" in Oregon is the tallest known currently living Douglas Fir at 326 ft. (99.4 m) tall; and the "Queets Fir" in Olympic National Park has the widest known currently living trunk at 16 ft. (4.85 m) in diameter.

The Coast Douglas Fir or Coast Douglas-fir, Pseudotsuga menziesii var. menziesii, is an evergreen conifer variety of Douglas Fir (Pseudotsuga menziesii) native to western North America, from central California north through Oregon and Washington to British Columbia, Canada. In California, it is found in the Klamath Mountains and the Cascade Range, the California Coast Ranges as far south as the Santa Lucia Mountains in San Luis Obispo County, the Sierra Nevada as far south as the Yosemite region, and a southernmost small stand in the Purisima Hills of Santa Barbara County.

In California the Coast Douglas Fir variety and species Douglas Fir (Pseudotsuga menziesii) occur from near sea level along the coast to 5,900 feet (1800 m) in the Sierra Nevada. Eastward they are replaced by the variety named Rocky Mountain Douglas Fir (Pseudotsuga menziesii var. glauca). The variety named Mexican Douglas Fir (Pseudotsuga menziesii var. lindleyana) is endemic to central and northern montane Mexico.

Coast Douglas Fir trees are not frequently planted in residential gardens, they get very large and need to be provided with substantial space to grow. Douglas Firs are the second-tallest conifer species in the world after Coast Redwoods (Sequoia sempervirens). Trees 200-250 feet (60-75 meters) in height and trunks 5-6.6 feet (1.5-2 m) in diameter are common in old growth forests. Coast Douglas Fir commonly lives more than 500 years and occasionally more than 1,000 years.

Brackens (Pteridium) are a genus comprising several species of large, coarse ferns. Ferns (Pteridophyta) are vascular plants that have alternating generations, large plants that produce spores and small plants that produce sex cells (eggs and sperm). Brackens are in the family Dennstaedtiaceae, which are noted for their large, highly divided leaves. They are commonly found on moorland. Brackens are cosmopolitan, being found on all continents except Antarctica and in all environments except deserts. The genus probably has the widest distribution of any fern genus in the world. In the past, the genus was commonly treated as having only one species, Pteridium aquilinum, but the recent trend is to subdivide it into about ten species.

The Coast Live Oak (Quercus agrifolia) is an iconic, majestic tree that serves as a cornerstone for wildlife and the surrounding ecosystem. It is easily-recognized by its gnarled branches and grand canopy. The Coast Live Oak flowers each spring and its acorns attract a wide variety of birds and butterflies - over 270 species rely on these trees for habitat and food.

With its rich green foliage and unique branching pattern, the Coast Live Oak is a favored choice for both residential and commercial landscapes. These resilient trees can live for centuries, often surpassing 250 years, and can grow impressively tall, reaching mature heights ranging from 30 to 80 feet.

It is one of the only California native oaks that thrives in coastal environments, it enjoys fog and mild winters. In the first year after planting, water once a week. Then, reduce it to once a month until it reaches about 10 feet tall. After that, avoid watering directly during summer.

Coast Live Oaks like to have their roots shaded. When they're young, surround them with mulch, rocks, or smaller native plants. Some California natives, such as Toyon and Manzanitas, do well as "understory" plants under the Coast Live Oak. Fallen oak leaves provide natural mulch for the tree. Don't fertilize oaks. They'll amend the soil over time with their own leaves and build the natural mycorrhizal fungus in the soil they need to thrive. Gradually, they become islands of natural fertility that improve the health of the nearby plants.

Scrub Oak plays a vital role in supporting biodiversity by attracting birds and a diverse range of butterflies. Its ability to thrive in various conditions and benefits to local wildlife make it a valuable addition to gardens.

It is a medium-to-small oak. Its green leaves are leathery on the surface and somewhat hairy on the underside. Scrub Oak is a versatile plant that thrives in full sun to part shade. In cooler regions, it remains compact, while in warmer areas, it spreads out and grows several meters high.

Scrub Oak benefits from a thick layer of oak leaves as mulch with a few large rocks. Refrain from summer watering to mimic its natural drought-tolerant adaptation.

Canyon live oak is a species of evergreen oak that is found in the southwestern part of North America, notably in the California Coast Ranges. It is the most wide-spread oak in the state. Its ultimate size and shade are determined by its location within the state. This tree is often found near creeks and drainage swales growing in moist cool microhabitats. Its leaves are a glossy dark green on the upper surface with prominent spines; a further rapid identification arises from the leaves of Canyon live oak being geometrically flat. They are often sympatric with Quercus agrifolia and several other oak species. Fossil data supports a much wider distribution throughout the western United States during the early Holocene period. Native Americans used the acorns of this species as a food staple, after leaching of the tannins; moreover, its roasted seed is a coffee substitute. After forest fires, Canyon live oak regenerates vigorously by basal sprouting, and the clonal diversity of this species has been shown to be high. Alternate common names for this taxon are Canyon oak and "Golden-Cup Oak".

Quercus dumosa is a species of plant in the Fagaceae family. This shrub/small tree goes by the common name Coastal sage scrub oak. It is found in Mexico and the United States. It is threatened by habitat loss. The species Quercus dumosa lends its name to the eponymous plant community Quercus dumosa chaparral, in which Coastal sage scrub oak and toyon often co-dominate. It is easily confused with other scrub oaks such as Quercus berberidifolia, with which it may hybridize.

This plant is an evergreen shrub growing 1 to 3 meters tall from a large, deep root network. The leaves have spiny or toothed edges. The fruit is an acorn up to 1.5 centimeters wide. Some individuals produce large crops of acorns, and some produce very few fruits. The acorns are dispersed by gravity as they fall from the tree, and by animals that pick them up, such as squirrels and jays. Animals eat them immediately or cache them for later. The acorns tend to germinate easily. Reproduction via seed generally occurs only in very moist years.

This oak grows primarily in sandy soils such as sandstone near the coast. Its habitat is often chaparral. This oak sprouts vigorously from its stump and root crown after wildfire and develops a large canopy within a few years after a fire event. It sometimes codominates with Ceanothus species as early as four years after a fire. This oak also does well in the absence of fire.

Leather oak (Quercus durata) is a small, drought-adapted oak species endemic to California. This shrub oak, in the Fagaceae (beech) family, typically grows in serpentine soils and is often found with manzanita in chaparral habitats. It thrives in mountainous regions but is well-suited for gardens as it doesn't require serpentine soil and can tolerate a variety of garden soils, including those with clay. Best adapted to dry, rocky, and nutrient-poor soils, leather oak can form low, dense thickets and is often used as an urban tree.

A keystone plant in its native ecosystem, leather oak supports a diverse range of wildlife species.

Quercus durata var. durata is the most common variety of Leather Oak. It tends to grow at elevations from 500-4900 feet, primarily in the central Coast Ranges. The other variety, var. gabrielensis, is a rare plant restricted to the Transverse Range. Leather oak is often found on serpentine soils. However, in the garden this plant does not require serpentine soil and can tolerate garden soil as well as drought and clay-rich soils. However, it is best adapted to relatively dry, rocky, nutrient-poor soil. Most individuals remain short, under 15 feet, and have small, densely organized leaves.

Engelmann oak (Quercus engelmannii) is a moderately fast-growing tree, typically evergreen but sometimes drought-deciduous in hot summers. Native to Southern California, this rare oak has lost much of its range due to suburban development. It primarily survives in San Diego County, with smaller populations in Pasadena, Orange County, southern Riverside County, and Baja California.

This oak thrives above the dry coastal plain but below 4,200 feet, where winters can be colder. Its thick, leathery blue-green leaves provide year-round color and complement gray-green landscapes. Mature trees develop stunning, gnarled trunks and wide-spreading branches, making them a striking addition to open spaces.

Engelmann oak can be tricky to grow—it prefers dry soil but stays green year-round if it has access to groundwater or nearby irrigation. It requires plenty of space, full sun, and tolerates various soil types.

As a keystone species, Engelmann oak supports an extensive array of butterflies and birds, playing a vital role in Southern California ecosystems. It pairs well with native plants like ceanothus, coffeeberry, and silktassel.

The Garry Oak (Quercus garryana), also known as Oregon White Oak or Oregon Oak, is a member of the Fagaceae family (Beeches, Chestnuts and Oaks). It has a range from the mountains of Los Angeles County northward to British Columbia, Canada, particularly in the foothills of the Siskiyou and Klamath Mountains, the Coast Ranges of Northern California, and of the west slope of the Cascades. It grows from sea level to 210 meter altitude in the northern part of its range, and at 300-1800 meter in the south of the range. There are three recognized varieties with largely overlapping ranges. The tree is named after Nicholas Garry, deputy governor of the Hudson's Bay Company, 1822-35. In the northerm part of its range it is an attractive tree, sometimes reaching 90 ft. but more often 50-60 ft. In the southern part of its range it is more often a shrub to 20 ft. It has large, lobed leaves which it drops in winter. It makes an excellent tree or shrub for mountain gardens and is important for wildlife.

The California Black Oak gets its name from the dark bark color of mature trees. It has distinctive, deeply lobed leaves that turn brilliant shades of yellow and orange in the fall. It is a large deciduous tree that can grow up to 80 feet tall. It also has a large, spreading root system.

Black Oak acorns are an important food source for a wide range of wildlife, including birds, deer, squirrels, and other mammals. It is also a host plant for butterflies and moths. It is a drought-tolerant tree with low moisture requirements. Black Oak grows best in acidic soil.

The Valley Oak (Quercus lobata) grows into the largest of North American oaks. It ranges over the hot interior valleys of California where there is a water table within reach of the roots.

Valley Oaks grow quickly, reaching 20 feet in 5 years, and 40 feet in 10 years, and up to 60 feet in 20 years. Mature specimens may attain an age of up to 600 years. Its thick, ridged bark is characteristic and evokes alligator hide. The sturdy trunk of the Valley oak may exceed two to three meters in diameter and its stature may approach 100 feet in height.

The branches have an irregular, spreading and arching appearance that produces a profound leafless silhouette in the clear winter sky. During autumn, leaves turn a yellow to light orange color but become brown during mid- to late fall.

In advancing age, the branches assume a drooping characteristic. Its pewter-colored rippled bark adds to the attractive aesthetic of this species.

Typically, leaves are five to ten centimeters in length and are roundly and deeply lobed. The leaf width is approximately one half its length. Each leaf is matte green, with a pale green underside; moreover, the leaf is covered with abundant soft fuzz, yielding an almost velvety feeling. When a fresh leaf is rubbed or broken, an aromatic scent is exuded, evoking a forest odor. The wood is a dull brown approaching yellow.

Over most of the range, acorns fall in October. A variety of mammals and birds eat them, including the Acorn Woodpecker, Western Scrub Jay, Yellow-billed Magpie, and California Ground Squirrel. Like many oaks, Valley Oaks can tolerate wildfires. Although smaller individuals may be top-killed, most resprout from the root crown.

Valley oak tolerates cool wet winters and hot dry summers but requires abundant water. It is most abundant in rich deep soils of valley floors below 600 meters in elevation but can also be found at elevations up to 5,600 ft.

Valley oak is found in dense riparian forests, open foothill woodlands and valley savannas. Commonly associated trees are Coast Live Oak, Interior Live Oak, Blue oak, Black Walnut, California Sycamore and Ghost Pine. The Valley Oak is widely distributed in the California Central Valley and many smaller valleys such as the San Fernando Valley.

Because of its eventual size, it may not be appropriate for the average residential garden. Best not to provide irrigation within 30 feet of established valley oaks. They'll often absorb too much water, causing limbs to break off.

They are messy but beautiful. Best to plant near a water source.

Island oak (Quercus tomentella), also known as island live oak or channel islands oak, is an evergreen tree in the Oak family (Fagacea). A smaller oak tree in stature, the leaves are hairy (tomentose) on the upper and lower surfaces, toothes, and large compared to other oaks. Young twigs are also hairy, yet mature bark is gray and furrowed. Mature acorns have rounded tips and are also quite large compared to other species.

Endemic (limited) to six islands off the coast of California, it is also federally listed as a rare species because of its limited distribution in the wild. Island oak's natural habitat is Island canyons, slopes and bluffs. Oak trees support a larger number of wildlife than any type of tree in our state. Multiple mammals, birds, amphibians, and pollinators use oak trees for food and shelter. Indigenous People ground the acorns to make flour, after leaching out the tannins; they may also have roasted and ground them and used it as a coffee alternative.

In the garden it is fast growing and trouble-free. It is best used near the coast, but can tolerate inland conditions within about 20 miles of the coast if given some protection and a little extra water during dry times, especially when the young plant is getting established. The large leaves and dense shade create unfavorable conditions for understory plants; plant island shrubs and perennials with similar growing conditions next to it, rather than under it for better results.

Interior Live Oak (Quercus wislizeni) is a slow-growing, evergreen tree with a distinctive broad crown. The glossy dark green leaves and reddish-brown bark give it a formal look.

In winter and spring, the oak blooms with green and white flowers. The tree's long, narrow acorns serve as a food source for deer.

Interior Live Oak is a resilient and adaptable species. It thrives at elevations ranging from sea level to 5,000 feet, making it an essential part of diverse ecosystems throughout California. Interior Live Oak grows in part to full shade and prefers dry, loamy soil.

California Buttercup (Ranunculus californicus) is a perennial herb with glossy, deep yellow flowers featuring 9 to 17 petals. Native to much of California, Baja California, Oregon, and Pacific coastal islands, it blooms in late winter to spring. Two varieties exist: Var. californicus grows 1–2 feet tall, while Var. cuneatus forms a low ground cover.

This buttercup thrives in borders, meadows, and with native annuals or bulbs, needing little summer water. It self-seeds easily and can be propagated from seeds. Occasionally, nursery plants are available. A beautiful, low-maintenance addition, its seeds can even be toasted for culinary use.

Rhamnus crocea is a species of buckthorn (Rhamnaceae). It is endemic to western North America. This evergreen shrub is typically one to two meters in height. R. crocea typically occurs in chaparral and several other vegetation communities below 3,000 ft. The flowers are not showy; this species is planted for the berries. You may need more than one plant to ensure pollination. It is spiny so consider where you place it. The leaves are small, round, dark green on top and brown or yellow on the underside. The berries and small spheres, bright red.

Hollyleaf Redberry (Rhamnus ilicifolia) is an evergreen native shrub that grows in the foothills and mountains of southern and central California, the Sierra foothills, and the foothills west of Sacremento Valley. It primarily grows at elevations from 500 to 6600 feet. It was formerly considered a subspecies of Rhamnus crocea but is now considered a separate species. Their ranges overlap considerably, and they resemble each other superficially.

This plant is reasonable to grow if properly sited. Plant in part shade or full sun on rocky slopes, or at least with plenty of rocks surrounding it. It seems to prefer part shade in the drier parts of its range.

It can tolerate summer water up to 1x per month. However once established, it's usually happiest without any supplementary water, but in a spot where it can run its roots over to an irrigated area or a place with a little more natural moisture, such as a creek or rain gully. The flowers are inconspicuous; the plant is grown primarily for its springtime bright and shiny red berries. These berries are an important food source for birds.

This plant has small leaves with sharp points along their edges, resembling small holly leaves (thus its common name). These leaves give this plant significant deer resistance. This shrub is quite versatile in garden landscapes, from wildlife habitat to erosion control to hedges and barriers.

In optimal conditions, Hollyleaf Redberry can grow from a 1-gallon container to 3 feet tall in two years.
