>I did lose a C x powellii in my school garden that had lasted several years (it was a pink one, not a great flower) but the C x powellii album bulb I got last year and put in one of my home gardens survived. I can't say it is as vigorous as the bulbispermums but maybe it needs time to settle down as crinums sometimes do when they lose roots. I also planted a small "Super Ellen" not far from the house wall, I want to see it make a huge flower spike one day like it is supposed to be able to do, it sounds like a massive plant and since it was backcrossed onto bulbispermum I think, it has a good chance of being hardy, and it is in a protected spot anyway. Years ago I saw a large patch of powellii in an abandoned garden in Boulder. In the city (not the foothills, which are like Zone 8). And there are, or were, enormous plants of C. bulbispermum in a yard in south Denver. That inspired me to try them, but I gave the bulbs away when I remade the front bed. The plants get very large.
