Cryptantha micromeres is a species of flowering plant in the borage family known by the common name pygmyflower cryptantha. It is native to California and Baja California, where it grows in woodland and chaparral. Cryptantha micromeres is a hairy annual herb growing a branching stem to heights between 10 and 50 centimeters. The leaves are up to 4 centimeters long, variable in shape and covered in bristles. The inflorescence contains clusters of tiny bristly white flowers only a few millimeters wide.

Cryptantha microstachys is a species of flowering plant in the borage family known by the common name Tejon cryptantha. It is native to California and Baja California, where it grows in several types of habitat, including chaparral in the coastal and inland hills and mountains. It is an annual herb producing a branching or unbranched stem 10 to 50 centimeters tall which is coated in hairs and bristles. The hairy leaves are linear to oblong in shape and up to 4 centimeters long. The inflorescence is a length of bristly developing fruits tipped with open flowers with five-lobed white corollas just a few millimeters wide.

Cryptantha muricata is a species of flowering plant in the borage family known by the common name pointed cryptantha. It is native to California and adjacent parts of Arizona, Baja California, and Nevada, where it is known from many habitat types. It is an annual herb producing a branching 10 centimeters to one meter in height which is coated densely in rough and soft hairs. The leaves are linear in shape and no more than 4 centimeters long. They have hairs and bristles, some of which have bulbous bases. The flower cluster is a length of very hairy developing fruits tipped with a cluster of small five-lobed white flowers.

Slender Cryptantha (Cryptantha sparsiflora) is a native annual herb that grows in southern and central California. It tends to grow at elevations from 0-4000 feet.

Torrey's Cryptantha (Cryptantha torreyana) is a native annual herb that grows in northern, southern and central California. It tends to grow in open places and slopes and , at elevations from 1500-7500 feet.

Cucurbita digitata is a species of flowering plant in the squash family known by the common names fingerleaf gourd and bitter squash. It is similar to Cucurbita californica, Cucurbita cordata, Cucurbita cylindrata, and Cucurbita palmata and all these species hybridize readily. These species form the only restricted xerophyte species group in the genus Cucurbita. Each member of this species group is native to the Southwestern United States and Northwestern Mexico where they are relatively uncommon. Each group member is found in hot, arid regions with low rainfall. They prefer soil that is loose, gravelly, and well-drained. C. digitata is native to northern Baja California at higher elevations, northern Sonora, Mexico, southern Arizona, and southwestern New Mexico. The juvenile leaves of C. cylindrata, C. cordata, C. digitata, and C. palmata show a high degree of similarity, but their mature leaves are visibly different, as are their root structures. C. palmata and C. digitata are sympatric, with C. palmata separating the ranges of C. digitata at the juncture of Baja California, California, and Arizona. C. digitata fruits are clear green mottle that turns yellow at maturity, striped, and round. It was first identified by Asa Gray in 1853. Cucurbita digitata is a hairy vining plant with sharply palmate leaves having five fingerlike lobes. It is quite similar in appearance to its close relative, the coyote gourd Cucurbita palmata, but the lobes of its leaves are usually more slender. It has curling yellow flowers up to 5 centimeters wide. The fruit is a dark green squash, rounded or nearly rounded, with mottling and distinct white stripes. The bitter fruit is very distasteful and generally not edible, although a few animals may hesitantly eat the flesh while trying to get at the seeds. Each white seed is about a centimeter long and at 35% protein and 50% fat is a nutritious food.

Cupressus arizonica, the Arizona Cypress, is a species of cypress native to the southwest of North America, in the United States in Arizona, southwest New Mexico, southern California, and the Chisos Mountains of west Texas, and in Mexico in Coahuila, Chihuahua, Durango, Tamaulipas, Zacatecas and northern Baja California. In the wild, the species is often found in small, scattered populations, not necessarily in large forests. An example occurrence is within the Sierra Jurez and San Pedro Mrtir pine-oak forests of Mexico, where it is found along with Canyon Live Oak and California Fan Palm. It is a medium-sized evergreen tree with a conic to ovoid-conic crown. It grows to heights of 10-25 meter, and its trunk diameter reaches 0.5 meter. The foliage grows in dense sprays, varying from dull gray-green to bright waxy pale blue-green in color. The leaves are scale-like, 2-5 millimeter long, and produced on rounded (not flattened) shoots. The seed cones are globose to oblong, 15-33 millimeter long, with 6 or 8 (rarely 4 or 10) scales, green at first, maturing gray or gray-brown about 20-24 months after pollination. The cones remain closed for many years, only opening after the parent tree is killed in a wildfire, thereby allowing the seeds to colonize the bare ground exposed by the fire. The male cones are 3-5 millimeter long, and release pollen in February-March.

Cuscuta californica is a species of dodder known by the common names Chaparral dodder and California dodder. It is native to western North America. Cuscuta californica is a parasitic vine which climbs other plants and takes nutrition directly from them via a haustorium. The dodder resembles a pile of yellow-orange straw wrapped tightly around its host plant. It is mostly stem; the leaves are reduced to scales on the stem's surface, since they are not needed for photosynthesis while the dodder is obtaining nutrients from its host. It bears tiny white flowers which are only about 3 millimeters wide, and fruits which are even smaller.

Cycladenia (Cycladenia humilis var. humilis) is a native perennial herb that grows in central and northern California. It tends to grow in sandy flats and talus slopes, at elevations from 3900-9200 feet.

Cane Cholla is one of the most common native species of cholla cactus in California. There are two recognized Varieties: Var. parkeri is found in desert transition chaparral adjacent to the low desert of San Diego County and northern Baja, northward to Santa Barbara County where it grows at elevations from 0-5,200 feet. Chollas tend to hybridize freely, and determinations of species and varieties can be difficult. Var. parkeri is generally distinguished by its erect habit and long, straight segments. The segments are usually 3-5 times longer than wide. The flowers are generally yellow, sometimes with streaks of green or orange. The fruit is dry and inedible.

Cystopteris fragilis is a species of fern known by the common names brittle bladderfern and common fragile fern. It can be found worldwide, generally in shady, moist areas. The leaves are up to 30 or 40 centimeters long and are borne on fleshy petioles. Each leaf is divided into many pairs of leaflets, each of which is subdivided into lobed segments. The underside of the leaf has many rounded sori containing the sporangia.

Datisca glomerata is a species of plant native to California, Nevada, and Baja California known by the common name Durango root. It is one of only two to four species in the plant family Datiscaceae. It is an erect perennial herb with distinctive long, pointed, often sharply serrated leaves. It is said to superficially resemble Cannabis species. Its yellowish green flowers grow in clusters from the axilla of the leaf, where it joins the stem. A thick stand of the plant can form a medium-sized bush. All parts of this plant are toxic and in some areas it is considered a noxious weed. It is reported to be poisonous to cattle. It is also one of a rare group of androdioecious species.

Datura wrightii, or "Sacred Datura", is the name of a flowering and poisonous ornamental plant of the Nightshade Family (Solanaceaes), endemic to southwestern North America. It is ubiquitous throughout the South Western United States specifically but is observably most abundant within Southern California. It is sometimes used as an (often powerfully) intoxicating hallucinogen. Datura wrightii, as well as other members of the botanical Datura genus are sub-classified as a 'deliriant' hallucinogens which are virtually all anticholinergic drugs (specifically antimuscarinics). This class of hallucinogens are known for causing considerable disturbances in cognition, perception (especially visual and auditory) as well as a multitude of psychological facets relating to memory and attention.

Additionally, antimuscarinics like sacred datura also frequently lend themselves to the induction of morbid, frank and highly-realistic external visual hallucinations and illusions, along with disorientation, photophobia, confusion, moderate to severe impairments in judgment, psychological acuity and behavior, sporadic or periodic agitation, and perhaps most notably; a strong reality obfuscating delirium. Pharmacologically, the bulk of the psychoactive and perceptual presentations in datura's deliriously intoxicating effects seems to be linked particularly to the plant's antagonism (chemical inhibition) of the muscarinic acetylcholine receptor M1, or simply; the "M1 receptor" within the central nervous system (mostly the brain) where the function of the highly pertinent brain chemical; acetylcholine is blocked and/or inhibited from exerting its normal, natural function on the receptor.

The plant is a vigorous herbaceous perennial that grows 30 centimeter to 1.5 meter tall and wide. The leaves are broad and rounded at the base, tapering to a point, often with wavy margins. The flowers are the most striking feature, being sweetly fragrant white trumpets up to 20 centimeter (8 inches) long, often tinted purple, especially at the margin or in the throat. There are five narrow points spaced symmetrically around the rim. It can bloom from April to October. The fruit is spiny and conspicuous. In clear weather, flowers open at nearly full dark and wither a few hours after sunrise the following morning; in cloudy weather or in part shade, they may open earlier and last longer. A closely related species, Datura discolor, is limited to the Colorado Desert (a subdivision of the Sonora Desert) and is very similar in appearance. Datura wrightii is also often confused for or mistakenly conflated with the Datura innoxia species, however innoxia usually occurs further north and is also more common as a gardening plant whereas wrightii seems to be exorbitantly feral.

Southern California has historically been the site of various "toloache" (datura)-based native religious complexes by local indigenous peoples such as the Chumash, the Hopi, Tongva, and the Kumeyaay, among others. Certain ethnobotanists hypothesize or maintain that some of these California datura religions are very old, even when compared to other ingenious entheogenic substance use throughout the world. Datura wrightii is considered to be sacred to numerous tribes like the ones mentioned due again, to its very powerful visionary (and despite its inherent dangers); conspicuous entheogenic or thematic subjective and perceptual effects. These mind-altering, often archetypal experiences have served as a foundation for the mythologies of folklorish figures like Chinigchinix among the Mission Indians, and the beliefs and practices of the ethnographically-labeled "Datura Cult" of the Chumash. The Chumash datura complex in particular remains to be perhaps the most well-documented anthropological assessment and investigations by westerners into sacred datura's ethnobotanical ritualistic uses by indigenous peoples in the the U.S. The plant was utilized in sacred ceremonies and rites of passage for the younger members in several of the aforementioned tribes. In regards to the documented Chumash approach to datura, when a boy was 8-years-old, his mother gave him a preparation of "momoy" (an entheogenic datura concoction) to drink. This was supposed to be a spiritual challenge to the boy to help him develop the spiritual well-being required to become a man. Not all of the boys survived due to the high-risk of potentially lethal toxidrome from the anticholinergic toxicity which often results in dysrhythmia (usually an accelerated/fast heart-rate) or depressed breathing capabilities (acute respiratory depression), as it greatly impacts both the central and peripheral nervous systems due to the widespread layout of muscarinic receptors throughout the body (lungs, brain, heart, etc.) as well as the vitalness of their proper functioning.

The physical outcomes of antimuscarinic poisoning is often worsened by fervent elevations in body temperature (hyperthermia), urinary and gastrointestinal faltering, severe dehydration and ''drying', polydipsia (insatiable desire to hydrate oneself) or adipsia (pathological apathy or disregard towards hydrating oneself), bizarre behavior (sometimes violent), aimless or fugue wandering, akathisia, functional visual blindness, along with a possibility for lasting corneal damage as well as just general semantic or mental incoherency or emotio-cognitive 'flatness'. There can also be a paradoxical waxing and waning periods or intervals between immobility and restless, suggestibility and combativeness, confusion and lucidity, etc. Besides decreased mental stability, physiological poisonings and death, even among users who survive, especially ones who continue to use the plant; sacred datura and its related species have also long been associated with dementia, twilight confusion, madness, infirmity, socioethical perturbations in personality, capriciousness, ardent devilment, cunningness, hermitry, nocturnality, moonlight, asceticism, muteness, sacrality, malevolence, femininity, prowess, sensuality, lust, 'power' and witchcraft/sorcery; particularly necromancy (contacting forces of the underworld).

The Zuni people have also been reported using the wrightii species for ceremonial, magical, and divinatory purposes. For example, root pieces would be chewed by a robbery victim to determine the identity of the thief through a proposed divinatory ritual or practice. The powdered root is also used by rain priests in a number of ways to ensure fruitful rains for the land's flora and fauna. From a spiritual and symbolic standpoint; the plant is not only associated with crepuscularity, nightfall and lunar phenomena, but also water, and thus rainfall and cloudiness or precipitation are common themes in rituals.

It is one of North America's most historically relevant entheogens, particularly when considering the additional species of datura spread throughout the continent which contain the same phytochemical (tropane) alkaloids. Although perhaps not as recognized within western culture as the infamous Datura stramonium specimen, d. wrightii has still been used for its hallucinogenic effects by modern westerners; often in reckless attempts at exploiting the plant's psychoactive (deliriant) effects recreationally. Often this is performed through oral administration (as opposed to topically or smoked), and in carelessly high doses. Datura wrightii also appears to be the same species that was taken by various members of the notorious Manson Family cult and social commune led by Charles Manson in the late 1960s. It was purportedly repeatedly used in Spring of 1969 by Tex Watson and Paul Walkins (only months prior to the Tate?LaBianca murders) due to its proximity to the Spahn Ranch hippie-settlement in Los Angeles County.

Since the advent of the internet however, with the increased access to information and educational resources on the datura's substantial dangers and the acknowledgment of different (safer) types of hallucinogens, this has inevitably led to a notable decrease recreational use and experimentation by users in western drug culture and 'psychonauts', namely due to the severe physical risk and psychological dangers of using it casually. But also, ultimately due to the near-universally reported unpleasant, flustering and dysphoric qualities of the hallucinogenic trips themselves. "Pleasant" or enjoyable recreational experiences with any species of the datura genus is fairly rare, or at least cooccurring alongside other uncomfortably unsettling peripheral effects or phases of discomfort or disturbance. Usually prolonged after-effects tend to also be another strong deterrent of casual experimentation.

The main active ingredient is Scopolamine; also known as "Devil's Breath" when present in its isolated/extracted form, especially when extracted from Brugmansia species by criminal groups in Colombia for poisonings and robbery. Scopolamine is produced by a various other nightshade plants in other regions of the world (like Brugmansia is South America) owing to the alkaloid's extensive scope of cultural lore and social influence as a result of its nearly identical effects and societal outcomes or perspectives even cross-culturally, such as the reputation antimuscarinics have traditionally held even in western cultures via scopolamine-containing plants of the Old World such as belladonna, henbane, mandrake, etc.

Daucus pusillus is a species of wild carrot known by the common names American wild carrot and rattlesnake weed. It is similar in appearance to other species and subspecies of wild carrot, with umbels of white or pinkish flowers. The taproots are small, edible carrots. This is a common plant found along the west coast of North America from Baja California to British Columbia; as an example occurrence in Baja California, D. pusillus occurs in association with Mimulus aridus and Adiantum jordanii.

It most often grows at elevations from 700-5600 feet in the Peninsular, Transverse Ranges, South Coast ranges. In the drier parts of it's range, it grows most often on north facing slopes, and in partially shaded areas underneath scrub oaks or other larger shrubs.

This is a difficult plant to find in nurseries, but not too hard to grow from seeds. It's striking blue flowers bloom in late spring and early summer.

Delphinium patens is a species of larkspur known by the common names zigzag larkspur and spreading larkspur. It is a wildflower limited mainly to California. Plants grow typically 20 to 50 centimeters tall and bear up to 36 flowers each. The stems are mostly hairless, have reddish bases, and bears leaves on the lower half. Each leaf is divided into 3 to 9 lobes. The flower has dark blue sepals, the latter ones reflexed. The spur at the back of the flower is 4 to 8 millimeters long. The cleft at the center of the flower has white or yellowish scattered hairs. The elongated fruit is one or two centimeters long and contains pitted seeds.

Delphinium purpusii is a rare species of larkspur known by the common names Kern County larkspur and rose-flowered larkspur. It is endemic to California where it is known only from Kern and Tulare Counties in the region where the Sierra Nevada meets the Mojave Desert. It grows on rocky cliffs and talus. This wildflower reaches between one half and one meter in height. The erect thin stem has deeply lobed leaves around the base and a small, narrow flower cluster of generally ten to 20 flowers at the top.

Two of them, ssp. kinkiense and ssp. thornei, are endemic to San Clemente Island, one of the Channel Islands of California. The former, which is sometimes called Delphinium kinkiense ssp. kinkiense, is treated as a federally listed endangered species. Although it is in fact rarer than ssp. kinkiensis, ssp. thornei does not have a federal or state listing.

Channel Islands tree poppy (Dendromecon harfordii) is a flowering shrub or small tree and one of the most popular native plants with gardeners. It blooms with an abundance of  bright yellow flowers that contrast with sparse blue-gray oval leaves on  thin, branching stems. The flowering season is winter to spring but throughout most of the year, it can be covered in showy flowers. 

Channel Island Tree Poppy is spectacularly beautiful, easy to grow, and very fast growing. It can grow to 6 feet in two years. It likes full sun and well-draining soils, though it also does well in dry part-shade. It likes gentle slopes and flats. It is very tolerant of summer water for its first two years, but when mature, it's best to reduce it to 1x / month or eliminate supplemental water completely, especially if the plant is in partial shade.

Bush Poppy (Dendromecon rigida) is an attractive compact shrub native to California and Baja California. It is covered in petite, buttercup-like yellow flowers during the winter-spring blooming season. Bush Poppy is a fast-growing shrub that maintains a rounded form with light pruning. The Bush Poppy?s narrow, grayish-green leaves are evergreen, providing year-round color in the landscape, even when not in bloom.

This plant is robust and easy to grow when planted in the right dry, sunny conditions. It is commonly found on dry, rocky slopes and is known to be a fire-following plant. In the garden, it does best when planted in full sun in very well-draining soil. The Bush Poppy needs little to no supplemental irrigation once it is established, making it an appealing choice for a waterwise garden.

Deschampsia danthonioides is a species of grass known by the common name annual hairgrass. It is native to western North America from the Yukon Territory and British Columbia, through California and the Western United States, to Baja California, and also to southern South America in Chile and Argentina. The annual bunchgrass grows in moist to drying areas such as pond edges, meadows and grasslands, in various habitat types such as montane and chaparral. Deschampsia danthonioides has stems growing solitary or in loose clumps up to 40 to 60 centimeters tall. The inflorescence is a narrow to open array of thin branches bearing small V-shaped spikelets.

Deschampsia elongata is a species of grass known by the common name slender hairgrass. It is native to western North America from Alaska to Wyoming to northern Mexico, and South America in Chile. It grows at all elevations, often in moist areas. It is a perennial grass forming dense clumps sometimes exceeding a meter in height. Most of the leaves are located in a tuft about the base of the stems. The flower cluster is a thin row of V-shaped spikelets arranged parallel to and mostly flat against the stem.

Descurainia pinnata is a species of flowering plant in the mustard family known by the common name western tansymustard. It is native to North America, where it is widespread and found in varied habitats. It is especially successful in deserts. It is a hardy plant which easily becomes weedy, and can spring up in disturbed, barren sites with bad soil. This is a hairy, heavily branched, mustardlike annual which is quite variable in appearance. There are several subspecies which vary from each other and individuals within a subspecies may look different depending on the climate they endure. This may be a clumping thicket or a tall, erect mustard. It generally does not exceed 70 centimeters in height. It has highly lobed or divided leaves with pointed, toothed lobes or leaflets. At the tips of the stem branches are tiny yellow flowers. The fruit is a silique one half to two centimeters long upon a threadlike pedicel. This plant reproduces only from seed. This tansymustard is toxic to grazing animals in large quantities due to nitrates and thiocyanates; however, it is a nutritious in smaller amounts. The flowers are attractive to butterflies. The seeds are said to taste somewhat like black mustard and were utilized as food by Native American peoples such as the Navajo.

Western Ponysfoot (Dichondra occidentalis) is a rare native perennial herb that grows in Southern and Central California, primarily in the South Coast and Channel Islands regions. It tends to grow in slopes, at elevations from 200-1600 feet.

Machaeranthera asteroides (fall tansyaster) is a North American species of plants in the sunflower family. It is native to the southwestern United States (California, Arizona, Nevada, New Mexico, Colorado, Utah) and northern Mexico (Chihuahua, Sonora, Baja California). Machaeranthera asteroides is a biennial or perennial herb with a woody taproot. It often grows in a clump of several stems. Ray florets in the flower heads are white or purple, and female. Disc florets are yellow and bisexual.

Mimulus angustatus is a species of monkeyflower known by the common names purplelip pansy monkeyflower and narrowleaf pansy monkeyflower. It is endemic to California, where its distribution is scattered around the North Coast Ranges through the San Joaquin Valley and a section of the Sierra Nevada foothills. It grows in moist habitat in open areas, such as vernal pools and meadows, sometimes carpeting an open area with its tiny pink blooms. This is a petite annual herb growing in ground-level tufts with hair-thin stems barely a centimeter tall. Its herbage is green to reddish in color, the paired linear leaves spreading about 1 to 3 centimeters long. The tubular base of the flower is surrounded by a hairy greenish to red calyx of sepals. The flower corolla is pale to bright pink to reddish-purple with one or more large purple spots, and sometimes yellow markings, in the throat. The trumpet-like corolla may be several centimeters long, much longer than the stem on which it is borne. Research suggests that the population size of this wildflower is positively affected by disturbance of the soil it grows in, especially by the activity of pocket gophers; plants growing on disturbed soil have bigger flowers, fewer plant competitors, and more pollen on their stigmas from greater numbers of neighboring M. angustatus.

Diplacus aridus, is a species of monkeyflower with yellow blossoms. This species is native to Southern California and Baja California; in Baja California, M. aridus occurs in association with Daucus pusillus and Adiantum jordanii.

The bush monkey flower is notable for its cheerful orange and yellow blooms, said to resemble a monkey's face. It's also sometimes called sticky monkey flower because the leaves produce a protective sticky resin. It is a perennial subshrub with flowers that attract hummingbirds and bees.

This low-water plant tolerates a variety of soil types, as long as they are well-draining. In coastal areas, bush monkey flower likes full sun; plant in partial shade in inland gardens.

Grows best in sandy, coarse-grained or other fast draining soil. Prefers sun or part shade in coastal sites, and part shade in inland sites. Selected for the garden.

Diplacus fremontii is a species of monkeyflower known by the common name Fremont's monkeyflower. It is native to California and Baja California, where it grows in mountain and desert habitat, especially moist or disturbed areas. This is an annual herb with a thin stem growing 1 to 20 centimeters tall. The oval leaves are up to 3 centimeters long, the ones higher on the plant hairy in texture. The tubular base of the flower is encapsulated in a wide, ribbed, hairy calyx of sepals with pointed lobes. The corolla of the flower is reddish-purple with a darker pink throat with a yellow spot. There are occasionally all-yellow flowers. The flower is one to two centimeters in length.

Bush Monkey Flower (Diplacus puniceus) is a small shrub native to the coast areas of Southern California. It grows to about 2 feet high, has dark green leaves, and bright red trumpet-shaped flowers that can last for most of the year. However, the blooming period depends greatly on the rainfall pattern. It is an important food source for hummingbirds. It prefers full sun by the coast and part shade inland.

In most cases, this plant needs to go semi-deciduous in the summer. Direct watering in late summer or early fall with often kill this plant. Best to let it go dormant for the hottest months of the year, and then watch it come back with the rains. Healthy plants will readily reseed.

Blue Dicks (Dipterostemon capitatus), also called Wild Hyacinth, Purplehead and Brodiaea (alternate spellings, Brodiea, Brodeia) occur in Arizona, California, Oregon, Utah, New Mexico, and northern Mexico.

This species has three recognized subspecies: D. capitatus subsp. lacuna-vernalis, Dipterostemon capitatus subsp. capitatus, and Dipterostemon capitatum subsp. pauciflorus. Dipterostemon capitatus is an herbaceous perennial, growing from an underground corm. It has 2 or 3 leaves, which are 4-16 inches long.

The flower cluster is head- or umbel-like, and dense. It usually contains 2 to 15 flowers, which have a blue, blue-purple, pink-purple, or white perianth. The flower tube is 0.1-0.5 inch and is narrowly cylindrical to bell-shaped. Flowers have six fertile stamens, deeply notched, lance-shaped, white, angled inward, slightly reflexed at tip, with outer filaments wider at the base. It has a twisted and fleshy peduncle, a set of membranous, petal-like stamen appendages around the anthers, and angular black seeds.

It reproduces from seed and vegetative means in the form of cormlets. The cormlets are attached to the parent corm by stolons and are sessile, produced in the axils of the old leaf bases on the mature corm. Plants thrive in open disturbed environments and are a common post-fire succession species in chaparral.

Dirca occidentalis, or Western Leatherwood, is a deciduous shrub with leaves 3 to 7 centimeters in length. Yellow flowers emerge prior to leafing. It grows on moist and shaded slopes. It is rare and endemic to the San Francisco Bay area of California.

Downingia concolor is a species of flowering plant in the bellflower family known by the common names maroonspot calicoflower and fringed downingia. This showy wildflower is endemic to California, where it is a resident of ponds and vernal pool ecosystems in the northern part of the state. This annual grows on a branching erect stem with small leaves at intervals. At the top of each stem branch is one or more flowers, each about a centimeter wide. The tubular flower has two long, narrow, pointed upper lobes which may be blue or purple. The three lower lobes are fused into one three-lobed surface, which is blue or purple with a large blotch of white in the center and blotches of maroon toward the mouth of the tube. There may also be speckles of yellow.

Draba cuneifolia is a species of flowering plant in the mustard family known as the wedgeleaf draba or wedgeleaf whitlow-grass. This annual plant is native to the southern half of North America where it grows in open, rocky fields and disturbed areas. The plant forms a basal cluster of leaves, which are thick, widely toothed, and coated in stiff hairs. It bolts one or more erect stems which may approach 40 centimeters in maximum height. Each hairy stem bears an inflorescence of up to 75 small white flowers that continue at intervals down the stem as the stem grows in height. At fruiting the stem is lined with many fruits on stalks, which are flat, green siliques up to a centimeter long.

Dudleya abramsii is a succulent plant known by the common name Abrams' liveforever. It is native to California and northern Baja California, where it grows in rocky areas in a number of habitat types. It is a fleshy perennial forming a small basal cluster of leaves around a central caudex. The thick, waxy leaves are triangular to oblong and usually pointed, reaching up to 11 centimeters in length, but often remaining much smaller. The entire rosette is generally only a few centimeters wide. The flower cluster is a mostly erect, branching stem lined with pointed leafs and bearing up to 15 flowers. The flower has five small, thick sepals at the base of five pale yellow petals each about a centimeter long.

Dudleya attenuata, common names including Orcutt's live-forever and Tapertip live-forever, is plant species native to California and to Baja California. Leaves of this species are clavate, up to 5 mm thick. Flowers are open rather than tubular, borne in cymes with only 1-3 simple branches, hence with fewer flowers than most related species.

Orcutt's Liveforever (Dudleya attenuata ssp. orcuttii) is a rare native perennial herb that grows in Southern California, primarily in the South Coast region. It tends to grow in bluffs, at elevations from 0-200 feet.

Dudleya blochmaniae is a succulent plant known by the common name Blochman's liveforever or Blochman's dudleya. This plant is native to California and Baja California, where it grows along the coastline. It grows somewhat erect, with cone-shaped, horn-shaped, or triangular succulent leaves along its stem. The plant may be brown, reddish-purple, or greenish. It bears a branching flower cluster with a few flowers per branch, each opening into a star-shaped bloom with five pointed white petals, sometimes with streaks of red. Dudleya blochmaniae ssp. brevifolia

Dudleya cymosa is a succulent plant known by the common name canyon live-forever. It is a distinctive plant sending up erect red-orange stems from a gray-green basal rosette. The small yellowish-red thimble-shaped flowers top the stems in large flower cluster. The plant is found in rocky areas in the low elevation mountains of California and southern Oregon. Some subspecies are considered threatened locally. Hummingbirds love this plant.

Fingertips (Dudleya edulis) is a slow-growing succulent, also known as string bean plant, lady fingers, and dead man’s fingers. The plant forms a cushion of upright, fleshy, finger-like leaves that grow from just below ground level, reaching 8 inches to 1 foot tall. The leaves are pale green or yellow-green, and their tips often turn orange or red during the summer. In spring, it produces branching clusters of small, white flowers on stems above the foliage.

Extremely drought-tolerant, fingertips is ideal for containers or rock gardens. It thrives in sun to part shade and well-draining soil. This plant attracts hummingbirds and hosts some butterflies and moths.
