Digging Dog has some interesting ones. Can't get mine to grow that well. What conditions do they really need?

Hoovb,
You might be abit too hot and dry for many of them. Most species come from high altitude areas with summer rain and peaty soils with acidic ph and subsuface water at the roots, and probably temperatures in summer that are cooler than most of inland southern California. In your location, they will probably do best with bright shade or dappled sun, a cooler exposure, and light well drained soil that is kept moist. You might also try cultivars such as 'Winter Cheer' which is winter blooming, and more likely to grow well in southern California. I am willing to bet that they mostly grow like weeds if you are in Sunset zones 23 and 24...
