Description
It is often desirable to add plantings around existing coast live oaks, and in these situations, we advocate the planting of other California native species and cultivars due to their horticultural compatibility. The companion plants included in this palette are well suited for perimeter locations where there is more sun exposure and where they can be planted with minimum disturbance to existing tree roots. These plants are also adapted to growing with seasonal rains and low amounts of supplemental water during the summer months.
