Imperial Masterpiece
I have several in training that were purchased from Wigerts. They are incredibly flexible. You can literally tie them in knots. They do well inside under lights in winter.I don’t have one, but I keep admiring the Vietnamese Blue Bells that I see on the Wigert’s website.
The spines are vicious and very long. Long and sharp is enough to deal with but they are long to the point of distraction.
