Maybe not possible but thought I would try. Got this from a plant trade, via a neighbor. Note on the plant said it "gets tall" and that it had survived four winters outside (definite plus!)
These may not be the best pictures but I can try again if it helps:
I've repotted it since I got it (just the other day in fact as that note also said it was still seting roots so I gave it about a month) and eventually want to put it in the ground.
