Bindweed

Bindweed, the name commonly applied by farmers and gardeners to the small Convolvulus arvensis with pink and white flowers, a tiresome field weed; to the large Calystegia sepium, with large white flowers, in hedgerows; and to Polygonum Convolvulus, the climbing buckwheat or black bindweed, an equal pest, only resembling the others in its twining mode of growth and in the shape of its leaves.
