Description
A compact evergreen shrub with small, stiff, often spiny-edged leaves and bright red berries. It usually feels tucked into the understory rather than standing out in the open.
Wildlife & pollinators
Birds eat the berries, and small insects visit the inconspicuous flowers. Dense twigs provide cover.
Habitat & range
Chaparral, oak woodland understory, coastal sage scrub edges, and dry canyon slopes across Southern California.
In the garden
Good for dry shade, wildlife plantings, and subtle understory structure. It is not flashy, but the red berries and evergreen texture are useful.
Propagation
From seed. Clean seed from ripe berries and expect slow, uneven germination.
