Do you think it might be one of the weedy species of Smilax? (Not all the species are weeds.) Also called greenbriers or catbriers, these tenacious, fast-growing vines eventually develop an extensive system of tubers (which can grow to about the size of yams, and in clusters) and knobby rhizomes underground. These evergreen to partially deciduous plants have thorns and waxy, heart-shaped leaves. The weeds can grow 6 to 30 feet and have tendrils that cling to supports. Control is difficult; the plant can grow back from rhizomes after being cut or burned, and animals spread the seeds. It is best to control them when young, and dig out the rhizomes/tubers. The waxy coating on the leaves makes it difficult for herbicides to be effective; however, you can try cutting down the weed and then waiting for new growth (about 1/2 to 1 foot tall) before applying herbicide. If you think this might be the plant, you might try contacting your county’s Cooperative Extension (if you are in the U.S.) for more advice about how to control. Hope this helps!
