Dioscorea batatas, Cinnamon Vine Question
When I was a kid the historic 1890s house we lived in (which is in the same city I live in now) had a vine with heart shaped leaves and little marble-sized tubers that formed along the vine. We used to pick them off and play with them. They were kind of slippery if you crushed them. I'm pretty sure it was a cinnamon vine (air potato vines sound like the tubers are too big and the vines too vigorous). I think at most the vines we had were 10' long, but probably shorter. They grew on a chain link fence. They seemed to stay in that one area, I never saw them anywhere else in the yard.
I went to research air potatoes (Dioscorea bulbifera) and cinnamon vine (Dioscorea batatas) because I thought my daughter would enjoy playing with the tubers the same way we did as a kid (not eating them, she's old enough to know not to eat plants in the yard). The articles I read on air potatoes said the vines can get to 70' in a single season when it is happy and that it is highly invasive in most areas of the south. The bigger tubers on air potato vine sounds cool, but I definitely don't want a 70' invasive vine.
I can't find any information on cinnamon vine's habits, though. I tried googling it but all the links were dead, I'd get a "blabblah.com cannot be found, please check the name and try it again".
Anyway, all this to say, I really want it but if it is going to turn into the new kudzu I'll be responsible and abstain. Are cinnamon vines very invasive? Also, is it likely to be what we had at the house I lived in as a kid?
