Judy I just want to wish you good luck with your crinum and thanks for trying them. I'm nowhere near your zone so can't vouch for potting. I know they dont like to be moved(when in they are in the ground)they adore water. I consider them giant rain lilies, they will bloom, bloom rebloom with adequate water. And like Anne said they do pup prolificly, and they do take up some real estate. Still love them!
