It's Passiflora (Passiflora Aphrodite's Purple Nightieâ„¢)
Pictures of the plant on this page if you scroll up/back a bit.
It's bigger now of course, but kind of folded over on itself on the roof as the wind caught it about a week ago. Still covered in blooms. Hope the frost takes it's time getting here, because I'm enjoying this plant way too much.
