Common Greenbriar

(Smilax rotundifolia)

Varieties of greenbriar are found in most tropical regions of the world. Common greenbriar is native to the eastern U.S., where it grows as long, thorny vines. Its shiny leaves are broad and heart shaped, 2 to 5 inches long.

It has spread all over the Eastern US, and as far west as Illinois. It has tendrils that it wraps around other plants so it can form dense thickets.

It is also called the "devil's wrapping yarn" because of the way it grows and because of its thorns.
