suggestions for ceanothus, tibouchina, more?
I have a garden with no irrigation in San Francisco. The areas I need to place plants in is mostly full sun, and the ground is rocky clay, heavily mulched.
I need smallish perennials to go under/around the following (and so may get some shade):
tibouchina (silver princess plant)
standard rose that will get watered
amaryllis belladonna (shady area)
thanks for any suggestions :)
