My mom is growing this vine; she said it was given to her from my cousin who uses it for medicinal purposes. She told me the name in Chinese but what's the English name? The rhizome looking thing is eaten in a couple of years but she eats the leaves now. The leaves are succulent type; kinda thick.

Is it possibly Fo Ti?...which would also be fallopia multiflora or polygonum multiflorum.....

Compare to Anredera cordifolia

If yes, it is naturalized from Florida to Texas. Also in southern California and in Hawaii.
In some country Australia, New Zealand, South Africa it is an serious invasive plant. Also in Hawaii.

For Australia http://www.youtube.com/watch?v...

If it is Anredera cordifolia is good to not dispose to the garbage the young plant or part of plant. This is a way to disperse non native plants.

USDA mentions three species of Anredera in US (area, shown only for two species)

but only two described in Flora of North America

The other Anredera vesicaria I think it is native in Texas. (?)

Oh, that's interesting...it does have the 'air bubils'......

Justin, I think you're right. Thanks.
