Quercus lobata
This majestic oak once covered the Santa Rosa Valley and many other fertile valleys throughout the state. Becomes large and picturesque with long drooping branches and beautiful thick, checked bark. Best in deep soils with room to develop. Wonderful planted for wildlife. Deciduous, long lived. Oaks are some of the greatest trees for birds. Oak titmice, acorn woodpeckers, and many other species utilize them for nest sites, cover, insects and acorns.
Quercus tomentella
The rarest of all California oaks, an ancient relict of the mainland, now confined to the Channel Islands, off the coast of southern California. Island oak is a small evergreen tree with a rounded canopy, 25 to 40 foot tall. Beautiful dark-green, shiny, leathery leaves with prominent parallel veins are edged with widely spaced teeth. Whitish woolly hairs cover the growing tips, undersides of leaves, and the caps of the 1 inch long acorns. A natural for gardens with coastal influence where it will be drought tolerant once established. Tolerant of many soil conditions, but attains full stature in deeper soils in sheltered locations. Oaks provide beauty, shade and food and cover for a wide array of wildlife.
Quercus wislizeni
Typically more compact in stature than the coast live oak, this evergreen oak has similar dark-green, leathery leaves, though often narrower and flatter. A native of dry foothills, the interior live oak has a range that extends throughout much California, and is the dominant live oak in the western Sierra-Nevadas. While it can flourish in the shade, it may remain shrublike. In full sun, its densely-foliated canopy has a pleasingly broad, rounded habit. This adaptable oak takes inland heat, and once established is drought tolerant and generally deer resistant. It tolerates clay, but does best in well-draining soils. Like other oaks, it’s a great habitat plant that supports a wide range of wildlife.
Ranunculus californicus
Cheerful harbinger of spring, this western native grows in vernally moist sites in a number of plant communities throughout California. Easy to grow perennial, sports bright green succulent foliage topped with slender stems 1 to 2 ft. tall and wide. A profusion of shiny, bright yellow blossoms bloom freely until soil dries out. Goes dormant with drought, returning in spring, often reseeding. Full sun to light shade. Excellent early pollen and nectar source, attractive to bees and other beneficials.
Ranunculus occidentalis
Native to open woodlands and meadows, this buttercup often occurs under deciduous oaks and buckeyes or on edges of forests. Perennial, with basal foliage, the flower stems rise 12 to 20 inches with bright yellow shiny petals. Has been surprisingly adaptable. Does fine with moderate summer irrigation, where it stays evergreen and long blooming. Once established can be allowed to go summer dry, where it will go dormant after setting seed, and returning with the winter rains.
Rhamnus crocea
An under-used evergreen shrub native to chaparral, woodland, and coastal-sage scrub communities in California. Spiny redberry can grow up to 6 feet tall and wider, but is typically in the 2 - 4 ft. height range, spreading to 6 ft. or more across. Small, leathery, dark-green ovate leaves give this tough shrub a delicate look once established. The flowers on both male and female plants are inconspicuous, blooming from late winter into early spring. Female plants produce sporadic, jelly-like red berries. Great for dappled light under oaks, or a dry, shady woodland slope with California fescue. Can tolerate more sun near the coast, but prefers afternoon shade inland. Drought-tolerant once established. Larval host for a multitude of butterflies and moths, including the pale tiger swallowtail butterfly, Ceanothus silk moth, and Hermes copper butterfly. Deer resistant.

The pendant flowers are tiny but numerous and charming on close inspection. The tubular flower parts are white and extend beyond the reflexed red sepals, and are highly attractive to hummingbirds and other pollinators. Red, bristly, globular fruits follow and are adored by birds. The bright green leaves often take on striking crimson colors in the late summer before going dormant with drought. Host plant to several butterfly species as well as the white-lined sphinx moth. Best with light shade and a little irrigation, though once established it is completely drought tolerant.
Ribes indecorum
Native to Southern California chaparral and coastal scrub plant communities from Santa Barbara County to Northern Baja. This vase shaped deciduous shrub features thick, aromatic, scalloped leaves and grows 6 feet or so tall and wide. Small clusters of white flowers cover the stems in November and attract hummingbirds, bees and butterflies. The fruits that follow are very appealing to birds. Plant in sun to light shade. Little to no summer water is required once established. While this currant is often summer deciduous, a little extra water will help it to retain most of its leaves all year long.
Ribes malvaceum
Chaparral currant is a tough and durable native shrub 5 to 8 ft. tall. This deciduous shrub will grow in full sun to light shade and is quite drought tolerant. Flowers early, often midwinter with dangling clusters of pink blossoms. Good early nectar source for hummingbirds. Berries attract many birds including grosbeak and mockingbirds.
