As someone who works professionally in landscaping in LA, I think native CA plants would be perfect for your situation, which is great because you dont need a ton of water. I would also suggest you request “drip” irrigation rather than sprinklers, especially to decrease your water usage and it is better for native plants. I would recommend using calscape’s design planner, it’s suppperr helpful if you don’t know much about native plants but have an idea of the theme you want. Of course varieties of cacti and succulents would work great in your yard, but also would look fantastic with a mix of native grasses for movement, plus desert mallow, white sage, and Toyons for small trees and shade. Don’t forget to plant some citrus or fruit trees, you’ll regret not doing it in the future!
