Erskine's Prairie Peace, a hybrid spinosissima, has become my Great White Whale of obscure rose hunting over the years. I did receive unrooted cuttings once from a very kind person, but was I unable to get them to take root. I"ve been told that difficulty in rooting such cuttings has been one of the reasons why spinosissimas are not as common commercially

Anyone know where I can purchase/obtain this Erskine's Prairie Peace for next spring? The only commercial vendor did not ship to the US.

Thanks!
