Hi. I'm new here so if I make some mistakes I hope someone will correct me. Can anyone tell me if there is a variety of Eremurus Stenophyllus that is cold hardy to Zone 2? I just bought one from a local greenhouse and the tag says that it is cold hardy to Zone 2, but everything I can find on the internet says that Eremurus Stenophyllus is hardy to Zone 4 at best. I'm in Zone 3a. Is it likely that this plant could be successful in my zone? Thanks for any help. The common name is Foxtail Lily.
