Lynn, thanks for the welcome and the link. I am amazed to find a forum just on these plants. My wife dug out a small pot about 25 years ago from some that were at her fathers house when it was sold. They have been just been growing and spreading with very little attention. We did have a large box (old sand box from when the kids were young) in the center of the back yard a few years back but a cold winter and hungry animals they pretty much got wiped out.
