The pure white trumpet like flowers of Calystegia silvatica are born on long stems which twirl around the stems and branches of surrounding vegetation; each flower is in the axil of a leaf. Leaves are bright green and arrow shaped, the calyx is enclose in two bracts, a characteristic of the Calystegia genus, and giving it it's name. The common English and the latin name suggest that this is a plant of the woodland, but in Skopelos it is found in damp places, notably where the small river of Skopelos town crosses the beach and the bindweed twirls around the tall stems of the tall reeds (Phragmites australis).
