Tropicals & Tender Perennials: Passiflora caerulea?, 0 by stephen_pace

Hi, I'm a bit new at this, but I have a couple of passion vines in my back yard and have a few questions. From the other threads I've read, I know that someone in this crowd will undoubtedly know the answers! First, I've attached a photo from last year. Am I correct in saying this is likely a Passiflora caerulea? If so, are there sub branches of this? I've seen other names like 'Blue Crown' and 'Blue Horizon' with similar looking flowers. Are these other names just cultivar names for Passiflora caerulea, or are they hybrids of some type? I'd be interested in hearing if mine is 'regular' or 'different'.

Next, do these plants spread from seeds or runners (or both)? Most of the passion flower sites I read said seeds only, but I've got them coming up everywhere and I have a hard time believing they aren't also coming up from the roots. Also, I'm assuming the seeds are in the fruits? My plants have green fruits that turn yellow and pretty much dry on the vine. If I open them, there are no visible seeds. Some photos I've seen show passion fruits with large seeds, so does that mean mine is sterile (again pointing to the runner theory)? Or are the seeds just too small to see?

This is my first post, and I'd like to thank the Dave's Garden regulars for the great Passion Flower information in other threads. I feel I've learned a lot already.
