According to my research, it is a variety that came about in Colorado, which has a pretty dry climate, and plenty of heat, especially in the eastern part of the state. From what I can figure, it might be drought tolerant enough, but I'm not sure about the heat. It gets cold enough long enough here that the big-tooth maples go dormant, as well as elms, soapberry, and other typically deciduous trees.
They are very pricey, though. I think this might just be a plea for someone to convince me one way or another, so I don't drop a bundle on a tree just to murder it.
From the wealth of knowledge here, I've learned that I live in probably the most difficult climate for bonsai, so my species options are very limited, especially for a beginner. Thanks for your input.
