I have had the most success with those varieties when I winter sow them. If you have fresh seeds now, I would plant them right before your first frost.

Fresh is best but there's many varieties whose seeds can be dried and stored. I soak dried seeds in orange juice for a couple days before planting them.

Thanks! I'll do both!
Karyn how long can cerula and incarnata be stored?

I couldn't tell you about caerulea seeds. My plants never produce viable seed but I've planted incarnata seeds that were a several months old and had ok germination. I did have better results winter sowing the incarnata seed. Myles has info on storing and germinating passie seeds on his site. It's the most informative passiflora site I've come across. Here's a list of some other links that might be helpful. http://www.passiflora.org/links.htm

Thank you so much for the link Karen! I am going to try a few methods and see what happens! : )
