Lin,
I suspect the link in DG is probably a mistake. It fits quite nicely in the group if everywhere it says inches is measured as feet instead. I'm not familiar the plant and when I got it home and read that it says the height was measured in feet, I thought at first it was a misprint. I do like the much colder temps it can survive seen in the links y'all provided. At 20F I might be able to situate it on the west side of a stone retaining wall and have it survive a winter here. That's if I'm successful growing it in a container until the size is unmanageable.
