A lot of Grace Stamiles early blooming diploid minis bloom reliably each year. I'll have to pull up my spread sheet when I'm back on computer to mention them all. As others have said, in this climate, optimum rebloom occurs when there is ample water, and rebloom happens more often with the early bloomers in this climate, because of the length of bloom season. Stella's Ruffled Fingers re blooms every year, along with Little Music Maker and Nano Probe, and there are others.
