Mine was exceptionally cold hardy! (3/25/2016)
After establishing the first year, the subsequent 3 years it was FANTASTIC! Survived 5 degree F (never above freezing for 3 days) winter. Is not evergreen since we can have harsh winters, but she always springs back and had just started to bloom in early summer and fall instead of just fall. We moved, but I was sure to take some seed pods with us in hopes of superwisteria 2.0!
