Smilax rotundifolia L.
Synonym(s): Smilax rotundifolia var. crenulata, Smilax rotundifolia var. quadrangularis
USDA Symbol: smro
USDA Native Status: L48 (N), CAN (N)
Ranges through much of eastern North America, from eastern Texas and eastern Oklahoma, east to northern Florida, and north as far as southernmost Ontario and Nova Scotia in Canada, where its limited range qualifies it for threatened status under Canadas Species at Risk Act (SARA). Numerous birds and animals eat common greenbrier fruits. The persistent fruits are an important late winter and early spring food for wintering birds, including northern cardinals and white-throated sparrows. Common greenbrier is a pioneer species that forms impenetrable thickets of prickly branches, which create good cover for small mammals and birds (USDA).
