First one I've had and I'm wondering if I should deadhead the first bloom spikes. Does it continue or rebloom if I do? Also, PF says it is zone 7, but mine wintered over nicely (this winter at least). Was I just lucky or might this be a variety that has done okay here in zone 4? Bought it at Otten Bros as a perennial. Thanks for your help.
