I’m in 6b and mine (purchased small from Bluestone Perennials last spring) never got big enough to bloom. I overwintered it inside and just planted it out to see if it can do any better the second year. In the meantime it’s a pretty underwhelming grass taking up space.

That’s too bad. Hope they do well for you this year. It seems like there is no nice fluffy ornamental grass flowers grow in our zone :(

I lost mine (planted in spring last year) over the winter, they did bloom a bit in the fall, but I shifted to M. reverchonii this year, because it's rock hardy here, and looks about the same.

Lost all mine in a bad winter.

Following up on my earlier comment, mine is dead. That makes two fails, both leaving in ground and overwintering inside. I'm out!
