Thanks for stepping in with the info, I've been out of town visiting sunny Florida filled with beautiful palm trees and just got home this afternoon. I planted it with a purple Oxalis, watered it in well, and left town. My experience is it gets rooted in best if left turned upside down for two weeks before hanging. I checked it today and the plant didn't do so well while I was gone. I gave it a drink and hope it pulls through.
