The Holy Grail of the Shade Garden
I found this patch of lady slippers on a walk through the mountains...They're rare and endangered, cannot be transplanted...I've been told at arboretums that the ladyslippers they had were only going to live for a single year! The plants had been dug from their native habitat and weren't going to survive the experience.

Thimblefarms also has lady slippers.
I know someone who has been growing mail-order lady slippers for a couple years. Apparently they can be grown from seed. I've been reading that when they're dug, any root damage kills the roots. I usually sever roots when I transplant, I don't think I'm going to do any ladysipper moving.
