Hollyleaf Redberry
Rhamnus ilicifolia
  
About Hollyleaf Redberry (Rhamnus ilicifolia) 26 Nurseries Carry This Plant Hollyleaf Redberry (Rhamnus ilicifolia) is a native shrub that grows in the foothills and mountains of southern and central California, the Sierra foothills, and in the foothills west of the Sacremento valley. It primarily grows at elevations from 500 - 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 not too hard to grow if properly sited. Plant on rocky slopes, or at least with plenty of rocks surrounding it, in part shade or full sun. 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 a an irrigated area or a place with a little more natural moisture, such as a creek or rain gully. The flowers are inconspicuous, and the plant is grown primarily for the fruits. If very happy, it can grow from a 1 gallon container to 3 feet tall in 2 years and will produce beautiful red berries in the spring. Its berries are an important food source for birds.
