zone hardiness for Mint Julep?
Long story short: I live near Springhill Nursery and every spring at this time they clearance all their excess catalog plants for 99 center per.... I picked up a bare root rose "Mint Julep" and wondered if anyone can give me a zone hardiness...i.e. not what the books say, but the farthest north you've had success with. I looked, and it seems like this one might be a warmer liking one, although some people online had planted it (with no comment on winterhardiness) in zone 5.
