They have it listed on their website, there is no shipping information so they may not ship plants. good luck

I have the plant but it's very small. It was attacked by the rabbits last season. I dug it up and potted it and if it comes back after this lousy winter and starts to grow again I may be able to send you some cuttings. I won't know if it survived until probably late April or early May and then wouldn't be able to get cuttings until the end of June.
