Ambrosia pumila is a rare species in the Asteraceae (Sunflower) family known by the common names San Diego Ambrosia and San Diego Ragweed. It is native to a very limited area in far southern California and Baja California where it grows in a variety of habitats along the coastal strip, inland valleys and foothills at elevations below 2,000 ft. This is a perennial herb not exceeding half a meter in height. The leaves are gray-green, fuzzy, and divided into numerous minute lobes to give a feathery appearance. They are up to 13 centimeters long, not counting the winged petioles. The flower cluster is tipped with staminate (male) flower heads above several larger pistillate (female) heads. The pistillate heads each yield usually one fruit, which is a fuzzy burr only a few millimeters wide with short, soft spines. However, it rarely produces viable seed, usually spreading by its rhizome, forming clonal groupings. It is adapted to dry habitat, but only on upper floodplain fringes, or adjoining depressions containing vernal pools or similar structures. It is a plant of open habitat and is not tolerant of heavy shade. If not given supplemental summer water it will become deciduous but will come back from the rhizome after winter rain. This is not an easy plant to find and infrequently used in residential gardens. It is important for restoration projects in areas of appropriate habitat, and it may be useful in gardens seeking to specialize in rare plants of southern California.

Hymenoclea salsola is a flowering plant in the daisy family known by several common names, including white burrobrush, cheesebush, and desert pearl. It is native to the southwestern United States and northern Mexico, where it is a common plant of the local deserts, where it thrives on sandy soil, alkaline environments, and disturbed sites. . This is a perennial shrub which forms a sprawling bush up to eight feet high. It has thin branches and narrow, needlelike leaves. The foliage has a pungent cheeselike scent when crushed, a trait which gives the plant the common name "cheesebush". It is covered in plentiful white or yellow flowers and then pearly, winged fruits in white, yellow, or pink. This species easily hybridizes with the common ragweed species Ambrosia dumosa.

Burrobrush (Hymenoclea salsola var. salsola) is a native shrub that grows in southern and central California. It tends to grow in dry flats and washes, at elevations from 0-5900 feet.

Western Serviceberry (Amelanchier alnifolia) is a beautiful shrub that grows primarily in Northern California and the Sierra mountains. Western Serviceberry has year-round interest, with showy apple-like white flowers that appear in spring, edible blueberry-tasting fruits in the summer, fall color foliage, and bare branches in the winter.

Western Serviceberry typically is a rounded shrubby form, though it can grow more upright, especially in shady areas. It can be pruned for either a flatter or more rounded, open spreading shape.

Western Serviceberry is fairly easy to grow in soil with excellent drainage, though it prefers loam or sandy loam. In its natural range, at higher elevations, it prefers full sun, needing little or no watering in summer, and is fast growing and long lived - reaching 6 feet in 3 to 6 years and lasting about 60 years. Outside its natural range, it prefers part shade and regular irrigation, and can be slow growing and short lived.

Western Serviceberry is an important food source for birds and animals, and is still grown commercially for human consumption.

Yerba mansa or lizard tail, is a perennial flowering plant within the family Saururaceae. It is the only species in the monotypic genus Anemopsis. It is native to southwestern North America. In early spring numerous tiny white flowers are borne on a cone which is surrounded by 4-9 large white spoon-shaped bracts that look like petals. As it matures, the visible part of the plant develops red stains, eventually turning bright red in the fall. Yerba mansa means "calming herb" in Spanish (yerba = "herb"; mansa = "calm or tranquil").

Yerba Mansa requires moist soil, so best to plant in streambeds, seeps or other damp areas. It goes dormant and basically disappears from late summer to early winter, and re-sprouts from the roots in late winter. It produces beautiful white flowers in the early spring that remain on the plant until it starts to go dormant in late summer. It will often spread out like a carpet throughout the damper soil, and choke out any other plants in the area, and in particular while it's blooming, it's quite beautiful.

Austin Griffiths Manzanita (Arctostaphylos 'Austin Griffiths') is a large evergreen shrub in the Heath family (Ericaceae). It is a hybrid between A. densiflora 'Sentinel' and A. manzanita 'Dr. Hurd'. It was introduced in the 1980's by Native Sons Nursery in memory of conservationist and naturalist Austin P. Griffiths.

The bark is maroon to dark red, with dark red stems, glossy sage-green foliage, and large clusters of of pale soft pink flowers. One of the earliest blooming manzanitas in early winter, it provides a valuable nectar source for hummingbirds, bees, and other pollinators. The berries are consumed by many mammals, and are also a food source for Indigenous Peoples.

The natural habitats for manzanitas are chaparral and openings in oak woodlands, which provide dry, sunny locations with excellent drainage.

This manzanita is striking as a specimen or informal hedge. Although it is a large shrub, it can be shaped and grown as a small tree. It prefers a sandy loam soil but does well in clay as long as it doesn't stand in water. More garden tolerant than 'Dr. Hurd', 'Austin Griffiths' accepts occasional irrigation but is exceptionally drought tolerant once established.

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

Howard McMinn Manzanita (Arctostaphylos 'Howard McMinn') is an evergreen shrub in the Heath family (Ericaceae). One of the last manzanitas to bloom, this medium-sized, fine-textured shrub has small leaves and tiny pink flowers that appear in late winter through spring. As it matures it will open up and reveal more of it's twisting, red colored branches.

It is a popular choice for gardens due to its tolerance for different soils, summer watering, pruning, and shearing. Combine with other species of manzanitas for a long bloom season. Howard McMinn is tolerant of different types of soils, however, waterlogged soils should be avoided. Stop irrigating after it is established; generally after one or two years. Extra irrigation in summer will result in a short-lived shrub. Prune in fall to remove dead or dying wood, or to improve the shape. Howard McMinn takes shearing well and can be used for a hedge. Plant in full sun in coastal sites, and sun or part shade if planted inland. Although manzanitas are naturally found in chaparral or open woodlands, this cultivar is one of the most tolerant of garden conditions.

Moths, hummingbirds, butterflies are attracted to the flowers, and animals eat the berries. Deer may eat the berries but generally leave the plant alone. The fruits are also edible for people. Traditionally they were dried and ground for a type of granulated sugar. They were also used to make cider. Manzanita is spanish for little apple, and the fruits do indeed resemble little apples.

Arctostaphylos hybrid. A medium size manzanita with all the characteristics of one of the larger species packed into a smaller specimen.
