Tiffany, I wish you could see this huge crinum bulb that I neglected to plant last year. I sat it in a large pot with some soil and forgot about it, as I wasn't sure where I wanted to place it. It' lying in a neglected area, under a tree, wherein some of the roots have come out of the bottom of the pot and grown into the soil. We had an extreme winter here. In late October, just out of the blue, we got 3 nights of sub-freezing temps. We barely had fall. That poor crinum looks a little tattered, but otherwise, is unfazed. I'm too embarrassed to take a picture of it, besides, we have a killer heat wave here with temps above 100 for the next couple of days. You just can't kill them as long, as the long thick roots can have some moisture.
Here, the leaves turn to nasty mush with the 1st hard freeze. I just leave them alone until they dry out during the winter and then cut them off. When the late spring frost nips the tips, I trim the frost tips off too, otherwise, the dead tips prevent the new leaves from opening properly for a while.
