The plant was new last spring and performed beautifully all summer.
I live in Zone 6a and even with a milder winter than usual I dont believe the plants survived.
The plants were bought at Bluestone Nursery and zone 6 was included in the hardiness zone but checking other sites now tat nI disvovered them dead , I see the lowest is zone 7.
Just a caution for anyone buying for zones below 7.They are not hardy
