I have been surprised by life(and especially flowers) emerging in the spring from things that looked like sticks.

Ahhh, thank you! I also have this Dend Usitea .. is it same principal? This one is about to flower on dead looking canes. Its a new acquisition from Yesterday. Outdoors summer. Cool dry winter by window?
