I have seed of this plant and looking for advice on germinating the seed? Would very much like to grow this plant for the Pipevine Swallowtails but having difficulty finding information for growing from seed. I realize it isn't a native here in the states but I've read it will grow in large pots, which is what I require. I already have Wooly and White Dutchman's Aristolochia plants.

All comments - advice much appreciated.

I have germinated this seed, as I grow it in my yard and it produces quite a lot of seed, unlike A tomentosa. It takes time. I would soak the seed overnight in warm/hot water and then put in damp sand (I use desert sand) and stratify for 4-6 months. Then you will want to take it out and leave it in the sand and put in a warm area for several months. Do another stratification for 4-6 months, and then you should experience germination. It takes 2 winters for seeds to germinate. You can also direct sow, and it will come up. It's very slow. I have the best results letting the seeds fall to the ground and leaving them to germinate on their own.

It has been a great host plant for the Pipevine Swallowtails here in NE OK. Needs shade in the heat of the summer.

to both of you! And welcome to the best forum on ATP, although I am biased. Most of the action goes on in the following threads so you may want to "watch" them:

The monthly butterfly thread is getting ready to flip to February, but I start the new thread and leave a notification when it's time to move to the next one. Since it's winter, we've been a little slow: The thread "January 2016 Butterflies, Moths & Larva" in Gardening for Butterflies, Birds and Bees forum

The bee (and other friends thread) has been going for quite some time. It, too has slowed down due to weather, but we get into some really fascinating conversations about pollinators and bugs in general: The thread "Beefriends(tm) and other Garden Guests - threeeeeeeee!!" in Gardening for Butterflies, Birds and Bees forum

The monthly bird thread has been the most active lately and we've even got international posters! Check it out for some pretty awesome bird pictures and conversation: The thread "Bird Photos - January 2016" in Gardening for Butterflies, Birds and Bees forum

This is just one forum on ATP, so be sure and check out the others if you haven't already! I'm just the moderator of this forum; hopefully, you will meet some of the others. Don't be shy about jumping in, contributing, or asking for help. This is a really friendly website and that's why so many of us spend our time here.

Bflymom, thank you so much for these very detailed germination instructions and growing advice. I am anxious to grow this plant but it looks like I will have a bit of a wait! I have plenty of partial shade growing spots. It is so nice to hear the Pipevine BF's will use this plant. Have you ever tried propagating by cuttings? ... Myles
