Description coming soon! Also known as: Primula hendersonii
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. In late winter to early spring, white to pink flower clusters emerge, followed by sticky, reddish fruits. 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.
