This weather-beaten bloom picture from a few days ago shows that the potential for rebloom (albeit very late) in this species cross. This isn't a big surprise since both parents have been reported as having rebloomed somewhere (never for me here in Maryland), and these four seedlings were the ones I'd posted on blooming indoors as seedlings. It'll be interesting to see how these seedlings behave as they develop into clumps and also how they perform as parents.
