Hairyleaf Redberry (
Rhamnus pilosa
) is a relatively rare native shrub that grows in San Diego in the Peninsular Range, at elevations from 500 - 5000 feet. Most frequently it grows in rocky north facing slopes.
It's a striking plant, closely related to
Rhamnus crocea
, but with a more upright form, and leaves that are grey green in the winter and spring, with somewhat hairier leaves and stems than either
Rhamnus crocea
or
Rhamnus ilicifolia
. It produces a beautiful display of bright red berries in May and June. In the summer its leaves turn a darker green. It appears to grow in full sun and part shade.
Unfortunately, this plant is not carried in nurseries.
