OHHHH one more thing. I have a question for Dave - John, Your Crinum will do just fine, as there are no hardiness problems with powellii at all, especially in your area. Planting them deep will make sure they get the moisture they require and it'll also keep the roots cooler which as a hardier species they should enjoy. The only problem with planting powellii deep is that it makes them very difficult to move or split with ease once they mature. Best Wishes, Dave
