Well! Just when you think you're on to something new! BAM!
I purchased a Ponsettia last year at Christmas. When the leaves fell off I pruned it back to nothing and kept it in the window. In early May I repotted it.
This sucker grows fast! When I got it the trunk (do you call it a trunk? It's a bush right?) was only about fourth of an inch maybe, and now its a good three quarters in diamiter. It has a light brown/biege color where the green stalk used to be.
This lil' tree definately has color going for it if nothing else.
