Coral Greenbrier (Smilax walteri) is a woody vine native to the Atlantic and Gulf Coastal Plain from New Jersey to East Texas. Among other locations, it occurs in the wetland forests of Alligator River, Pocosin Lakes, Mattamuskeet, and Swanquarter National Wildlife Refuges. Coral greenbrier produce red berries, adding a festive look to the browns and earth-tone colors of winter woodlands. The berries persist throughout the winter and early spring until hungry songbirds eat them. For years local residents have used these thorn-less vines to make Christmas wreathes. (Bob Glennonv)
