I have successfully grown a very, very sad wavy-leaved soap plant (Chlorogalum pomeridianum). She came from a project I worked on last fall that involved lots of ground disturbance, which then turned up lots of soap plant bulbs, which were mostly eaten by hungry animals. But not this one, who I saved and quasi planted, mostly just to see what would happen. She sat in her pot looking like a very dry, very hairy coconut for about five months, then finally sprouted these four very sad leaves. But, in the way of plants, nonetheless managed to bloom. I'm very proud of her, and will transplant somewhere with more soil depth soon. Also of note is that I was told that these guys only flower at night, but clearly this is not the case.
Yay for California native plants stolen (salvaged?) from national parks!
