Answer: Ceanothus, or California Lilac, is a relatively short-lived plant (about 7 years) so that might sway your decision in what you want to plant. Ceanothus are evergreen plants, especially attractive in the spring, with their blue to violet-blue flowers. You can purchase Ceanothus griseus horizontalis 'Anchor Bay' at Digging Dog Nursery, Box 471, Albion, CA 95410, (707) 937-1130, or Canyon Creek Nursery, 3527 Dry Creek Rd., Oroville, CA 95965, (916) 533-2166.
Some other considerations for your planting site include Arabis (Rockcress), Arctostaphylos (Manzanita), Fragaria chiloensis (Wild Strawberry), or Lysimachia. All will help hold soil, provide seasonal color, and are relatively carefree once established.
