I wish I had some Aristolochia seeds to share!

My A. tomentosas are huge, with one having colonized all the way down a long fence, and they bloom profusely every spring, but I've never gotten a single seed pod. I've opened the flowers up, and there are plenty of gnats inside, but they must not be what it takes to do the job.

I've also got a little A. fimbriata and A. clematitis, but the pipevine swallowtail cats eat them to the ground before they get a chance to bloom.
