QUESTION: I live in Seal Beach, CA.

Answer
Hi Peggy,
Thanx for the additional information.  Here's a partial list.  I've also included a reference to the California Cooperative Extension Service for Orange County which I think you will find to be a fountain of information specific to your area.  I hope this helps and please let me know if there is anything else I can do for you.
thx,
Tom

Lantana, purple sage, red yucca, achillea, aloe, lemon bottlebrush, cassia, pampas grass, coreopsis, tritoma, lavender, oleander, bird-of-paradise, matilija poppy (romneya), bush germander, agave, artemesia, iceplant, centaurea, dusty Miller, yucca, Bougainvillea, cacti, cape honeysuckle, wisteria, rosemary, santolina, olive.  One thing I always like to do is go to a really well-stocked nursery.  They will usually have a section for xerescaping.  This is very common in Southern California and Arizona.  I visit my cousin who lives near Palm Springs quite a bit and I've noticed the xerescaping themes.  Now, I know Palm Springs' climate is way different from Seal Beach but you still have the dryness.  I hope this helps.
