Planted 4 of these potted vines today ( 2 Dutchman pipe and two passion vines. Hopefully they will grow and provide some cats a meal and a place to grow up.

Yea! Do you know if the Dutchman's Pipe are the native ones? Down here in FL they sell the tropical ones, too. Problem being, the tropical ones are great for the Polydamas Swallowtails but too toxic for the Pipevine Swallowtails. I grow both kinds as does MOSI where I volunteer. Still, I've never had much luck raising Pipevine STs. Polydamas are a lot easier; sometimes I think they're near indestructible! Also, just an FYI to people who don't know - most passion vines are okay but I hear the caterpillars don't survive on ones with the red blooms. Just one of the many reasons I advocate native plants. Plus, in my experience, the butterflies tend to lay on the native varieties first. More familiarity, I guess?

Yes these are the tomentosa which is native here in Tennessee. I had to order them.

Oh, I grow tomentosa, too! I have two of them but one grows faster than the other. I had to order mine special, too but it's worth it for the Pipevine STs. An odd thing I found out last year - I don't know if you have Long-Tailed Skippers in your area but they will lay eggs on Aristolochia tomentosa. I don't know why but I saw an article from UF where a lady had it happen and asked about it. The plants have a similar feel to a human, but I thought butterflies tasted the chemicals with their feet so you think they would know the difference. But I have to keep a lookout for Long-Tailed Skipper eggs and get them to the right host plant.
