And yesterday Handsome Son found the plant stem outside on the step, evidently left there by a neighbor for me to do some magic with, he has great faith. No story on how it came to be separated from the parent plant, but I suspect that the two resident little dogs are involved. And I'm not sure what the name is, but any blogistas who can tell me, please do. It's a pretty common houseplant, name escapes me.
So I'll give it a chance, and put it, in water, among the other houseplants. I think plants like to be in a community of plants.
