I am thrilled to have P. edulis or a hybrid, especially for the fruit! I have P. Incense and one other unknown, possibly Caerulea. so my experience with leaves is both pretty much have the tri-lobed leaves from the beginning.

Yes, you can tell by the tendrils :) I have a few that have that single leaf shape.

Hey "L" good to see a name I recognize from the past :-) I am impatient to see what my plant turns out to be, but it seems the cold has kept the passi from growing faster. I'm sure once it gets a bit warmer it will start growing again.

Passiflora nigradenia is a passie that has single leaves. I am growing that one.

Beautiful passi sjn. I am growing p. Preciosa that is also single leaf. It grew a lot last year, but no bloom, then the vine died back, but it's now starting to grow again. The unknown vine above has only grown a bit and has three new small leaves. I look forward to finding out what it is once it grows up!

What did it turn out to be? I have young plants that I think are P. Edulis that look just like yours.

It's possibly P. Edulis. The latest leaves are 3-lobed, and I could have dropped some seeds there after eating a fruit provided at our CRFG's meeting. It's still in the same pot, but need to repot and relocate where it can roam.
