Tiffany, I didn't mean to burst your bubble. They grow well in full sun. But, if you have lighter colors, like the pale pink powellii, those look bleached out in full sun. That's why I recommended giving them some respite from the sun. Otherwise, crinums take a licking and keep on ticking--hot, dry, wet soil, high humidity--nothing fazes them. I foolishly planted some in a container a few years ago, not thinking about how huge those bulbs get eventually. I'm going to have a heck of a time getting them out of that pot before it bursts. I've got another mother bulb in another pot in a slightly neglected part of my yard that I'm trying to reclaim for it's shade. I've got a lot of plants to move this fall, because with the lose of 2 oak trees, they are in too much sun. We are sorely in need of rain right now.
Yep, Kabby is right about it's ability to withstand full sun and lots of water. I don't fertilize mine, but I wonder if it will bloom better if I do.
What can be better than lots more blooms.
