Laura,
I don't have any to dig for you but I think they start quickly from cuttings. I'll take a couple and see if I can't get them rooted in case you don't get any other offers here. I planted mine at the base of a palm and I'm letting the vines grow up and around it. The butterflys hover around it all the time.

Kate-if you can successfully grow them from cuttings, please, please tell me how! I have a small one promised to laura that's a sucker. I love this vine and her love for butterflies will really make this a spectacular addition, I think. Let me know how your technique works. I pull suckers all the time and if they have no roots and am not successful. Even with roots, I still add some roottone but it's a crap shoot! Once this vine takes off though OHH LAH LAH!
