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.
Rhamnus ilicifolia
A handsome evergreen shrub with small, dark green, leathery, serrated leaves. Found in the foothills and mountains of southern and central California, the Sierras and west of the Sacramento Valley up to 3,500 feet. Slow-growing, reaching 6-10 feet tall and wide, with a somewhat open, upright habit. Male and female plants are separate, producing inconspicuous yellow-cream flowers from spring into early summer. Female plants produce sporadic, gelatinous red fruits. Hollyleaf redberry can be planted in full sun to shade, but prefers a bit of relief from the afternoon sun in inland sites. It requires decent drainage and is drought-tolerant once established. Larval host for the pale swallowtail butterfly. Reportedly deer resistant.
Rhus aromatica
An arching, mounding native shrub related to sugar bush and lemonade berry. Early spring brings a profusion of soft yellow flowers followed by orange-red fruits relished by wildlife. The leaves turn shades of yellow, orange and red in the fall. Plant in sun to light shade where it is drought, cold and heat tolerant. Useful addition to the naturalistic garden, as a shrubby groundcover, along seasonally moist streams, and for erosion control. Used by the native people for basketry.
Rhus integrifolia
This sturdy native shrub or small tree is highly valued for its evergreen foliage and as a source of food for birds, bees and butterflies. Round, serrated, leaves, flatter than those of the sugar bush, cover this plant from head to toe.

Ranging in height and width from 6 to 20 ft., lemonade berry is very tolerant of pruning, either into a small tree or a low hedge. Cold hardy to about 20 degrees. Plant in full sun to part shade. Will be very drought tolerant once established. Fire resistant. Deer resistant.

The light green foliage returns in late winter followed by delicate clusters of bright yellow tubular flowers that mature to a reddish-orange. Makes a wonderful addition to any habitat garden. Hummingbirds and bees adore the flowers, and the golden berries attract birds. Tolerates a variety of conditions from creeksides to dry woodland foothills to higher elevations - and even snow. Grows 6 to 8 ft. tall and wide. Where it finds water, it can spread by suckers, but is highly amenable to pruning. Adaptable to sun or shade, but does best with afternoon shade and moderate to occasional summer water.
Ribes californicum
Undemanding, winter blooming, deciduous shrub, native to Coast Range mountains of California, from Mendocino County south to Orange County. Excellent choice for habitat gardens, where it provides abundant flowers and fruits plus thorny, protective cover. Variable in size, this spiny shrub can grow 4 - 6 ft. tall and wide. 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.

Ribes malvaceum ‘Rana White’
This unusual form of the chaparral currant has pure white flowers, not the typical pink flowers one normally sees. Forming an erect shrub of true green, aromatic foliage 6 ft. or more tall and wider. Winter and early spring bring short pendant racemes of the fragrant white flowers that are highly attractive to hummingbirds and pollinators. Clusters of sticky berries follow and are relished by birds. Though it will tolerate garden conditions, this currant is extremely drought tolerant once established. When allowed to go dry, this well-adapted species drops its leaves in late summer and leafs out again in late autumn. Moderate irrigation can make it almost evergreen. Plant in full sun to light shade. This species can be found throughout much of California in chaparral and on the edges of woodlands. Introduced by Rana Nursery.
