Polemonium micranthum is a species of flowering plant in the phlox family known by the common names annual polemonium or annual Jacob's-ladder. It is native to western North America from British Columbia to North Dakota to California as well as disjunct in the Andes of southern Argentina and Chile. It can be found in many types of shrubby habitat, such as sagebrush scrub and foothill woodlands. It is an annual herb with a branching or unbranched stem taking a matted, spreading, or upright form. The slender stems are up to about 30 centimeters long and the herbage is coated in short, soft hairs and stalked glands. The leaves are located along the stem, each divided into several small leaflets. The solitary flowers have small white or pale blue lobed corollas tucked within cuplike calyces of hairy, pointed sepals.

Polyctenium fremontii, the desert combleaf, is named both in English and Greek for its deeply lobed leaves, which almost appear to be pinnately compound. It takes the other portion of its scientific name from John C. Frémont. It is a small and compact plant native to the western United States. Leaves have forked hairs, and the distal end of the leaf often has a single hair at the very tip. It is a member of the broccoli family, and the white flowers therefore have four petals in the shape of a cross. The flowers appear in clusters at the ends of the stems. This plant is rather uncommon, but is among the first plants of sagebrush country in the inland western U. S. to bloom in spring. It is found on the banks of seasonal streams and similar places.

Polygonum douglasii is a species of flowering plant in the knotweed family known by the common name Douglas's knotweed. It is native to much of northern and western North America, where it can be found in many types of habitat, including disturbed areas. It has been found in Canada from British Columbia north to Yukon and east as far as Québec, and in the United States as far south as California, New Mexico, Iowa, and New York. Polygonum douglasii is known as a species complex, as there are many subspecies that may be better treated as species in their own right.

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.

Mesquite (Prosopis glandulosa var. torreyana) is a common subspecies of the small to medium-sized flowering tree in the legume family, Fabaceae. It is native to the southwestern United States and Mexico, but has been introduced to at least a half-dozen other countries. In California's Central Valley and deserts it is an important habitat plant for many species of wildlife. Honey Mesquite has a rounded crown and crooked, drooping branches with feathery foliage and straight, paired spines on twigs. In some settings it will remain a low growing shrub forming dense thickets that are used as refuge by rabbits, quail, and other animals. In other settings it grows as a tree that reaches 20-30 feet, rarely as tall as 50 feet. It is highly adapted to arid environments with a very deep taproot (up to 100 ft.) to reach underground water. The fruit is a nutritious "bean pod" that is valued by many animals and was eaten by native people of the desert. It has spines and caution should be used when deciding where to plant it. It is an essential plant for the desert wildlife garden.

Prosopis pubescens, commonly known as Screwbean Mesquite or Tornillo, is a species of flowering shrub or small tree in the pea family, Fabaceae, that is native to the southwestern United States (Texas, Arizona, New Mexico, California, southern Nevada and Utah) and northern Mexico (Baja California, Chihuahua, Coahuila, Sonora). In California it is found primarily in desert areas from Inyo County southward. It has light brown bark, usually short, straight spines (1-3 centimeter/0.39-1.2 inches), twice-compound leaves, and numerous, small, yellowish flowers appearing in elongate spikes. It is found along streams and valleys in deserts, particularly in damp or saline soil, and grows to about 7 meter (23 feet). It is distinguished from the very similar Honey Mesquite (Prosopis glandulosa) by its tightly twisted seedpods (legumes) which very much resemble turned screws. This morphology may have been an evolutionary defense against seed predators such as bean weevils (Bruchinae). Like Honey Mesquite, these seed pods are valued by wildlife and were eaten by native people.

The leaves on the upper side are dotted with punctures, i. e. are punctate. The shrub blooms abundantly in white or cream-colored flowers with clawed petals. Blooming continues from spring until the first frost. The fruit is an achene, a long plumelike structure up to 6 centimeters long. The plume is dispersed on the wind and by animals such as rodents. The shrub is drought-tolerant and the seedlings may actually survive better in years of below average precipitation. The Stansbury's cliffrose shrub provides valuable browse for many wild ungulates, including elk, mule deer, and desert bighorn sheep, as well as livestock. Many birds and rodents consume the seeds, with rodents caching them underground, where they may sprout later. It is used for revegetation projects in degraded habitat in its native region, and as an ornamental. It was used by Native American groups for a variety of purposes, the bark being worked into fiber for clothing, bedding, and rope, and the branches being made into arrows.

This species closely resembles other members of the genus that have leaves with three "leaflets" ("trifoliate" leaves), including poison oak. People with sensitivity to poison oak should use caution around fragrant sumac.

The shape of the leaflets and the habit of the shrub make this species, like some other Rhus species, resemble small-leafed oaks (Quercus). The plant is deciduous and exhibits good fall color.

Golden currant is a small to medium-sized deciduous shrub with golden spring blooms. The flowers and fruit of this fragrant and attractive shrub make the golden currant a valuable wildlife plant. Hummingbirds, butterflies, and bees are attracted to the golden yellow trumpet-shaped flowers. The fruit is an important food source for many bird species as well as small mammals like squirrels and chipmunks. The berries are also used in pies, preserves, and other dishes.

Golden currant is very easy to grow and spreads readily, making it a good choice for revegetation, hedging, and groundcover applications. It grows best in moist conditions and benefits from partial shade, irrigation, and mulching in drier areas. On the coast, it prefers full sun. Inland, it prefers part shade and does best when surrounded by mulch, and grows well under oaks and in mixed chaparral. Once established, golden currant needs no special care.

Nodes along the stems are armed with spines which may reach 2 centimeters (0. 8 inch) in length. These are spines, not prickles, as they are derived from leaf material rather than from the plant epidermis (skin). The thick, leathery leaves have generally rounded blades divided shallowly into three or five lobes and dotted with glandular hairs. The small blades are borne on petioles. The inflorescence is a solitary flower or raceme of up to four flowers. Each small flower is a tube of white or yellowish sepals with smaller, similarly colored petals inside. The fruit is an edible berry one half to one centimeter (0. 2-0. 4 inch) wide which ripens yellow, then reddish or purple.

Rosa minutifolia is a rare species known by the common names Baja rose and small-leafed rose. This is a very spiny, dense shrub native to the chaparral and maritime succulent scrub plant communities of Baja California and barely crossing the border into San Diego County where it's habitat has been almost completely destroyed. It is being propagated at the San Diego Botanic Garden as a conservation measure, and it is grown elsewhere as an ornamental. The branches of the shrub are gray to red-tinted and covered in long and short spines. The shiny toothed leaves are composed of small leaflets only about half a centimeter wide. The blooms are generally bright pink with many yellow-anthered stamens and masses of prickles on the undersides. It is slow growing and individual plants remain fairly compact, unlike other wild roses. Though very drought tolerant, it accepts some summer water and will often bloom in response. It has a very long flowering season; with supplemental water it is essentially year round. It's a good choice for drought tolerant gardens especially in the southern coastal counties.

Woods' Rose (Rosa woodsii) is a native shrub that grows in Northern, Southern and Central California, primarily in mountainous areas including the Cascades, Sierra Nevada and Transverse Ranges. It is fast growing and long-lived, grows in an upright form to a height of 3 feet, with active growth during the spring and summer. Flowers are pink, striking and very fragrant, and bloom in the late spring. Leaves are medium green and deciduous. It tends to grow in moist places, at elevations from 3500-11500 feet. It has straight sharp thorns.

Woods' Rose needs moisture, but once established can be watered once a month in the summer. It tolerates clay but does best in moist loamy soil. Because of the spines and its tendency to sprawl, it can be pruned annually in winter.

Birds are attracted to the fruits, and Woods? Rose hosts a number of butterflies & moths, a likely total of 58.

Woods' Rose (Rosa woodsii var. ultramontana) is a native shrub that grows in northern, southern and central California. It tends to grow in moist places, at elevations from 3500-11500 feet.

Woods' Rose (Rosa woodsii var. glabrata) is a native shrub that grows in southern California. It tends to grow at elevations from 3500-11500 feet.

Tehachapi Rose (Rosa woodsii var. gratissima) is a native shrub that grows in southern and central California. It tends to grow at elevations from 3500-11500 feet.

Rumex hymenosepalus, commonly known as canaigre, canaigre dock, ganagra, wild rhubarb, Arizona dock, and tanner's dock, is a perennial flowering plant which is native to the western United States and northern Mexico.

Salix exigua (Sandbar Willow) is a deciduous shrub reaching 13 to 23 feet in height. The leaves are narrow, green, to grayish with silky white hairs when young. The flowers emerge as yellow or white catkins in late spring, after the leaves appear. The fruit is a cluster of capsules, each containing numerous minute seeds embedded in shiny white silk.

Like most willows, Sandbar Willow it is moisture-loving. It will tolerate a variety of soils and poor drainage. It grows in full sun and spreads by shoots to form dense colonies so it will eventually spread to occupy any wet soil that it can reach. Use with other wetland trees, shrubs and grasses.

It is host to a wide variety of pollinators, including butterflies, moths, and some gall-forming wasps. Some birds, such as the Least Bell's Vireo and Southwestern Willow Flycatcher, prefer to nest in large, dense willow thickets.
