I have found several ditch banks around here that are covered in passion vines, and I have been wanting to try the fruit, but I had no idea how to tell when it was ripe. I thought they were supposed to change color or something, so I've been waiting. I guess I'll just go pick some and try to find some ripe ones!
Also, which part of the fruit do you use to make your jams and jellies?
Give them a try. I guess it is the part around the seeds, but I'm not sure about the whole process.
