Anyone in Zone 5/6 grow passion flower vine?
I have seen catalogs that advertise passion flower vine 'Maypop' as being hardy to Zone 5. But I have never seen them in anyone's garden and have never seen them in local nurseries, which makes me doubt they are really hardy here. They look too exotic and tropical to grow here, but I love the way they look.
Anyone grow them in zone 5 / 6? What has been your experience?
