I thought I had a Passiflora Caerulea. The pictures are an exact match for the leaves and flowers but mine didnt die back this year. It got down to 14 degrees at my house and they didnt even blink. I know the roots are hardy down to 10 degrees but I thought they were only evergreen to the 20's. Does anyone else have this plant?
