Jim Waddick, I can’t help you with information about xAmarcrinum in zone 5, but here in zone 7 it seems to take care of itself in the garden without any problems. I’m convinced enough of its reliability in our climate to have planted eleven of them to border a curved 40’ bed in my garden. None of the plants I know came with clonal designations. In fact, I have no idea how many xAmarcrinum clones exist. Now that I’ve grown the plant for several years, I realize that the ones I have have inherited the best qualities which their parents have to offer: in these plants the great flowers of Amaryllis belladonna are combined with the ease of culture (in our climate) of Crinum. Fortunately, the foliage is nothing like Crinum foliage: xAmarcrinum is much tidier, with foliage only a bit bigger than that of Amaryllis belladonna. It also inherits from the Crinum parent the ability to grow throughout the summer and then easily survive a winter dormancy. Yet the individual flowers are not so ephemeral as many Crinum flowers are. The local planting best known to me has been established for a long time, maybe decades. I don’t know when they begin to bloom, but I see them in full bloom annually in late October. The owner of the garden where they grow tells me that they continue until cut by severe freezes. You can see these plants here: http://jimmckenney.com/x_amarcrinum_in_a_local_gar… To judge by the size of these, I think my plants still have a few years of catching up to do.
