Come to think of it, there are succulents everywhere in Southern California. There are cacti in the wild landscape.
Large succulents in public places, like these on the grounds of California State University, Channel Islands.
Smaller varieties grow in residential gardens.
Thank you all for your thoughts and suggestions about what to do with the succulents MS gave me. I agree with Knitting Linguist and Caroline. I prefer the herb garden plants of the Mediterranean climate, but maybe there is a place for succulents.
