Title: Groundcover for Southern California clay slope
Answered by: Nan Hampton
Las Pilitas Nursery with stores in Escondido and Santa Margarita has an excellent article, "Simple erosion control for a hillside or garden slope", that has good advice about landscaping slopes and offers some suggestions for native plants for using in Southern California. Here are some possibilities from the list for clay slopes:
Arctostaphylos edmundsii (Little sur manzanita) grows in full sun and here are photos and information from Las Pilitas.
Baccharis pilularis (Coyotebrush) will grow in full sun and part shade and here are photos and information from Las Pilitas.
Ceanothus griseus (Carmel mountain lilac)
Ceanothus thyrsiflorus (Blue blossom) grows in part shade. Las Pilitas shows a cultivar, C. thyrsiflorus repens, that is low-growing.
Eriogonum fasciculatum (Eastern mojave buckwheat) grows in full sun and here are photos and information from Las Pilitas.
You can see other groundcovers listed by height on the Las Pilitas site.
