Eric, if you have a problem getting plants, I have always have had very good luck with seeds. Warm, moist conditions with bright light will get them out in a couple weeks. I've grown about a half-dozen similar species (but not Aristolochia galeata). All perished 2 years ago when the g-house froze. The only one left, planted outside, is the native one. My favorites were gigantea (spooky blooms) and elegans (very floriferous).
