When we lived in San Diego, California Nubia and I grew a lot of succulents and caudiciforms. We have been developing a collection here and learning how to grow them in this climate. Many do very well, a few can’t handle the high rainfall and/or temperature range.
Some of the plants that do best are as follows (to be updated with details):
Jatropha podigarica and multifida
Kalenchoe (various species)
