brittle bush
BRITTLE BUSH - encilia farinosa, sunflower family. Bright yellow flowers bloom March to June. Flower heads grow 2 to 3 inches wide in loosely branched clusters.  There are 8 to l8 rays surrounding the yellow center disk.  This member of the sunflower family grows 2 to 5 feet high forming a rounded, leafy bush.  Long, ovate, silver-gray leaves are 1 to 4 inches long.  Brittle, woody branches contain a fragrant resin.  These branches were chewed by Native Americans and  burned as incense in California's first  churches.   
COREOPSIS, BIGELOW'S - A species of flowering plant in the daisy or sunflower family, with the common names Bigelow coreopsis and Bigelow's tickseed, which is unique to California.  This plant is known from the southern California Coast Ranges, southwestern Sierra Nevada, Transverse Ranges, and the Mojave and Colorado deserts.  It is an annual herb that produces one to many stems with erect, stem-like clusters 10 to 30 centimeters tall.  The leaves are divided into narrow lobes which are sometimes subdivided, and most of the leaves are located at the base of the plant.  This plant was eaten as a raw or cooked green vegetable by the native Kawaiisu and Tubatulabal peoples of California.  Blooms March to May.
creosote bush
CREOSOTE BUSH - Larrea tridentata.  The bush may lose some of its waxy, resinous leaves during extreme drought, but never loses them all.  These leaves are especially pungent after a rain, and have been used as antiseptics and emetics by native peoples.  Its foliage provides refuge for crickets, grasshoppers and praying mantis.  How to grow a Creosote bush from seeds:  Place several of these seed capsules in a shallow pan cover with boiling water.  Let them soak overnight, and then place a few seed capsules in a pot with soil and start to water.  Thin out the extra seedlings and plant.  The bloom season is November to May.
FREMONTIA – Flannel Bush - This plant is found in numerous habitats across California at elevations between 1,300–6,500 feet, especially in chaparral and woodlands area and in Juniper woodlands.  It was a traditional Native American medicinal plant; the inner bark’s sap was used as a topical remedy for mucous membrane irritation or for gastrointestinal upset.  The wood was also used as a building and furniture material and the bark for cordage.  The plant is cultivated as an ornamental plant by specialty plant nurseries for planting in drought tolerant gardens.  They need good drainage, and no supplemental summer water when established.  Blossoms in the Spring.
prickly pear cactus
PRICKLY PEAR CACTUS - Opuntia  Occidentalis, Cactaceae/cactus family.  Members of the Opuntia genus are unique because of their clusters of fine, tiny, barbed spines called glochids. The fruits of most prickly pears are edible and sold in stores under the name "tuna."  Prickly pear branches (the pads) are also cooked and eaten as a vegetable.  They, too, are sold in stores under the name "Nopalito".  Because of the glochids, great care is required when harvesting or preparing prickly pear cactus.   Both fruits and pads of the prickly pear cactus are rich in slowly absorbed soluble fibers that may help keep blood sugar stable.  Prickly Pear Nectar is made with the juice and pulp of the fruits and is available at natural food stores.  Yellow flowers with white filaments appear May to June.
