That was grown out from seeds I received marked G. bohemicum Orchid Blue from a trade. The flowers are only about 1" across, the plant is only about 8" high, and spreads maybe 12" or so. It is a hardy geranium, I've had it growing for 4 or 5 years, now. I have over 35 different of hardy geraniums, but I just never questioned what this was, since I had it listed on a seed pack. I can see from the photos in the links that that is not what I have. I will take some photos in the spring, and maybe someone can ID it from those.
