I would imagine any of the red ones would do well, as I've read that hummingbirds are more attracted to red flowers. I think I've heard that the tacsonias are good for hummingbirds, which would be like antioquiensis, mollisima, "coral seas", "coral glow", and a number of others."Coral glow" would probably be good for your area as it is supposed to take heat better. Perhaps "Lady Margaret" would be good, as it's nice and red, and floriferous.
