Answer: I can't promise deer and horses won't eat them, but native plants are probably your best bet - they're less attractive to animals than some of their more exotic counterparts. In your gardening region, consider these trees and shrubs: California Sycamore, Western Cottonwood, Quaking Aspen, California Laurel, Manzanita, Western Redbud, Snowberry, Elderberry, Currant or Wild Mock Orange. For seasonal color, include these native perennials: Aquilegia (western columbine), Asarum (wild ginger), Erigeron glaucus (beach aster), Heuchera (coral bells), Lilium humboldtii (Humboldt lily), Penstemon (beard tongue) Romneya coulteri (Matilija Poppy, and Sisyrinchum bellum (Blue-eyed Grass). All are drought tolerant once established.
