I have several A. elagans (I think) seedlings to trade for plants or stuff. This is a tropical/subtropical vine, my mother grows them in FL to feed to caterpillars. The seeds are large by Aristolochia standards. She wasn't sure if it was A. gradiflora or elagans, but was pretty sure it was elagans. Vines are nice, pic available upon request. Looking for plants that will grow outside here in z-6 (Musa basjoo, for instance), but am open to suggestions.
