The uncommon California native holly leaf cherry makes a nice informal screen.

Since it is native to coastal chaparral between Monterey in California and the middle of the Baja California Peninsula, holly leaf cherry, Prunus ilicifolia, is right at home in Mediterranean gardens. Although it can be a nice refined hedge if not shorn too frequently, it is better where it has space to grow wild into a mounding shrub, and can eventually grow into an undemanding informal screen as high and broad as fifteen feet. Width is easier to limit with selective pruning than with shearing. Besides, unshorn plants bloom with clusters of minute white flowers in spring, and produce interesting deep red or purplish red cherries in autumn. Unfortunately, the cherries have very big pits with only minimal sweet pulp. The small glossy leaves have somewhat bristly teeth almost like those of some hollies.
