I love this vine but it is hard to find here. I was given a small one last spring. By the end of summer it was covering its trellis and blooming non-stop even in our heat. Unfortunately it did not survive its winter stay in our garage (sob). I had it in a pot with ordinary good potting soil. In some afternoon shade (our sun is VERY hot) and watered it when I watered all the other pots and that's all it wanted. They do not set seed usually. I understand their pollinators are ants--but from what I read most people don't get much seed. I wish I had--I miss my vine, it was also very well behaved compared to many I have!!!!

I have loads of seed (2005) and would be happy to send to anyone. Check out the new legislation for importing small seed lots. The links are on the UK Gardening forum and the Suggestions forum. I also usually have lots of different Passiflora and various Aristolochia (amongst others). If you are interested please put your ideas in the Suggestions forum.

This is my first year growing it but I read it may bloom the first year, but the second is better. I read that you can dig up the tubers it forms in the fall and store them til next year.

PS...and it can grow in a pot from what I read.
