yes, i have. Didn't do anything special- just kept it reasonably warm & moist. They didn't take all that long- maybe a month... it's been a couple yrs. I've done p. elata and 'amythyst'.

i started some from seed saved from fruit. it took a very long time to germinate them.

If by Pasionaria blue you mean Passiflora caerulea 'Blue Passion Flower' - I have a yard full of it. I brought one tiny plant with me when I moved here. It escaped its pot out the bottom one summer when I took the saucer away and left it sitting on the bare ground. Now I will never finish pulling it out of the woods. I like the flowers. Mine has never produced fruit tho this variety is supposed to be edible. It is amazingly winter hardy (only losing leaves when it gets down into the teens!) for a tropical. It is considered one of the most invasive of the invasive passion vines.

Wow...I'm not exactly sure if that is the one I'm trying to get to grow...That's all the seed package said.

They are so pretty....I think I might be able to just let it go crazy in my yard. lol ( I say that now....it's empty now).
Thank you all for your help! I appreciate that very much!

I bought a pack from Lowe's this spring. I put them inside a wet paper towel and closed it in a ziplock. At 78 degrees, it took about 3 weeks. Only one seed germinated. The rest turned to mush. It was the only really large, hard seed of the bunch. That vine is now 3' tall.
