Consult the California Garden Web for more information.Annuals and perennials: sunflower (Helianthus), strawflower (Helichrysum), impatiens, annual mallow (Lavatera).Bulbs, corms, tubers: gayfeather (Liatris), lily (Lilium asiatic hybrid).Trees, shrubs, vines: California wild lilac (Ceanothus), crape myrtle (Lagerstroemia).Fruits and vegetables: nectarine, okra, peach, pepper.Check irrigation timers for compliance with the current watering schedule.
