Chitalpa tashkentensis,, oleander, Lagerstroemia, arbutusunedo, manzanitas, choisya spp's, romneya coulteri, Iris douglasiana canyon snow, to name a few. Sunset lists plants by season of bloom and color, which you can cross reference with their natives/drought and heat tolerant lists. I'd also look into plants with white/silery foliage such as various sideritis spp's, salvia spp's, Centauria gymnocarpa, etc.

You are a treasure trove of ideas, thank you so much!

I love winter berry, flowers are small pink and white but seeds are big and white. Penny

Eucryphia nymanensis is not only drought tolerant, but covers itself with white blooms in August and September.

Just a peek at my leftover white oleander trees that line my driveway to give you an idea of how lovely such a common plant can be. I am praying I don't lose them all to Oleander Leaf Scorch, which is systematically killing all the oleanders in S. California. This is about half of how floriferous as they were about 2 weeks ago:

Great suggestions, thanks!

Love the oleander trees, I've never seen them like that before...it seems a lot of contributors to these forums don't like this old freeway plant standby...I think they consistently look good.
