Description

This is a rhizomatous perennial herb with a woolly stem growing to lengths of 10 centimeters to nearly a meter. It generally does not climb as do many other morning glories. The leaves are vaguely kidney-shaped to triangular and pointed, and reach a few centimeters in length. The foliage is covered in a short coat of woolly white hairs, giving the plant a light greenish gray color. The inflorescence holds a solitary white flower which is sometimes tinted with pink or yellow. The flower is 2 to 4 centimeters wide when open.
