I have had Moonlit Masquerade for many years now. It is a consistent performer for me in my zone 5 garden. It will occasionally rebloom for me. One of it's children (Mask of Eternity) is a consistent rebloomer. So if one is looking to hybridize with MM for rebloom in the North, I would cross it with another rebloomer to increase the chances of getting a reblooming child.
