Hubby brought me an air potato home.He picked it but had no idea what he was picking it off of.Its a large size like size of fist.My MIL grows some of these,but hers are always the size of walnuts& he couldn't tell me how it looked compared to hers.I can't figure how to tell it from cinnamon vine either& everything says they grow small tuber offsets.He says he picked this one.

this sites better.
it says the cinnamon vine has the small tubers about the size of a mans thumb, and when the leaves are crushed it has a cinnamon sent.
and the air potato vine's tubers are about the size of a golf ball or larger.
pretty neat. ive never herd of em before,
and the first link has a link about the colors, its at the bottom of the page.
