Interestingly, I *think* I have this growing in my garden. Intentionally. Brought home some of the aerial tubers from a permaculture site I visited. But the vines grow with no tubers. I maybe need a male/female but haven’t spent the time trying to figure things out. At that point I was interested in the pea-sized tubers, which you can eat like potatoes. I had no idea the root was medicinal!
