I have one of these to trade. It prefers a moist spot in partial sun to partial shade. It can also be grown in sites with average moisture as long it doesn't dry out. It can get quite big, so it needs some space.
I am most interested in trading for unusual perennials and small shrubs. That is vague, I know, but send me an offer on D-mail and we'll try to work something out. I would also accept named daylilies and irises (bearded, Japanese, Sib).
