Answer: It sounds from your description that your area would be classified as zone 9 or 10. I'm afraid that neither lilac nor viburnum would thrive there. Why not try something more adapted to your climate? (It sounds like a wonderful climate--especially since we had snow here in Vermont this morning!) Some good, and probably familiar, shrubs to try are: Camellia, winter jasmine, fatsia, crape myrtle, Japanese privet, Chinese privet, oleander, rosemary, and witch hazel.
