A climbing or sprawling perennial weed, the stems of the field bindweed grow up to 200 centimetres long, twining anticlockwise up any suitable support. Its leaves are shaped like arrowheads, and its flowers are funnel shaped and white or pink in colour. The flowers appear between May and September.
The field bindweed grows on waste ground, grasslands and cultivated areas. It often climbs cereal stalks at the edges of fields.
