Someone in the Hilo area just posted on the Facebook Passiflora group that he just bought two fruits at the market for the seeds. You have to apply to be a member to read the posts, though. That should take less than a day. I'll mention your post on the Facebook group.

Here is a link that might be useful: Facebook Passiflora group

The guy on the Facebook Passiflora group says that he can help you out with some seeds, but that you'll have to message him through Facebook.

If you have trouble contacting him this way, email me. (click "my page" and "email me" is you are new to Gardenweb).

Thank you! I was looking at the Facebook link that you showed me. I requested to join the group. I've been trying to find seeds on Oahu or fruit, but can't seem to find anyone that knows.
