Hollyleaf Redberry (Rhamnus ilicifolia) is an evergreen native shrub that grows in the foothills and mountains of southern and central California, the Sierra foothills, and the foothills west of Sacremento Valley. It primarily grows at elevations from 500 to 6600 feet. It was formerly considered a subspecies of Rhamnus crocea but is now considered a separate species. Their ranges overlap considerably, and they resemble each other superficially.

This plant is reasonable to grow if properly sited. Plant in part shade or full sun on rocky slopes, or at least with plenty of rocks surrounding it. It seems to prefer part shade in the drier parts of its range.

It can tolerate summer water up to 1x per month. However once established, it's usually happiest without any supplementary water, but in a spot where it can run its roots over to an irrigated area or a place with a little more natural moisture, such as a creek or rain gully. The flowers are inconspicuous; the plant is grown primarily for its springtime bright and shiny red berries. These berries are an important food source for birds.

This plant has small leaves with sharp points along their edges, resembling small holly leaves (thus its common name). These leaves give this plant significant deer resistance. This shrub is quite versatile in garden landscapes, from wildlife habitat to erosion control to hedges and barriers.

In optimal conditions, Hollyleaf Redberry can grow from a 1-gallon container to 3 feet tall in two years.
