Salvias will be your best bet, there are many, many sizes, shapes and colors to choose from. Your local nursery will know which are hardy in your area.

I would recommend native salivas that you would not have to water after getting them established.

Salvia clevelandii - is one of my and my hummers favorite.

Another two great natives are: Zauschneria california - Calif. Fuchsia and Galvezia speciosa- Island Bush Snapdragon.

All three of these are currently blooming, very sparingly right now, in my inland San Diego county garden. I only watered them to get them going and now only extremely rarely. They have no irrigation to them, so I once in a great while hand water them.
