greenbrier

Greenbriers, also known as Smilax, are a genus of about 300 species of woody or herbaceous vines found in tropical and temperate regions worldwide. These plants, belonging to the Smilacaceae family, are characterized by stems often covered in prickles and leathery leaves with untoothed blades. They produce small, white or yellow-green flowers, with male and female flowers growing on separate plants. The fruit is typically a red or bluish-black berry.1

Some species, like Smilax rotundifolia, are commonly called greenbrier and can form dense, impenetrable thickets. The young shoots of S. aspera are edible.12
