With our wet winters, it's hard to grow 'warm temperate' succulents. That being said, I've had great success growing Graptopetalum paraguayense and Dudleya cymosa. When in bloom, the hummingbirds will sit on the ground guarding Dudleya cymosa when in bloom.
As a genus, Dudley's are every bit the match for Echeveria in beauty. Sometimes much more.
