Mark, I've had Crinum asiaticum survive in the garden in Raleigh, NC (Zone 7b) for years, but they would get set back so far each winter that it made for very slow growth and no flowers. The only Crinum asiaticum hybrids successful in my climate also have Crinum bulbispermum in their ancestry, such as 'Twelve Apostles' and 'Sangria'.

Yesterday I noticed some of them resprouting from the base.
