Hi again, Janos! It's a small world. :-) It's hardy for me. I'm on the edge of Z5 / Z6. I planted it far away from my house, in my prairie where it receives full sun. It has survived for at least 4 or 5 years. Basically I neglect it. I didn't realize it was still alive until I saw it blooming this year. It blooms so early before my other prairie plants, that I never noticed it in previous years. My bearded irises near there are only just now starting to bloom. My point? I would probably enjoy this plant a lot more if it was closer to my house. It's a short plant. I bet it bloomed every year but I never realized it.
