This large, sprawling, yet often bushy and very common wildflower is easily identifiable by its large and showy white, pink, or purple pea flowers, and its winged stem with winged petioles leading to paired leaflets with a tendril between them. A European horticultural escapee, it is now naturalized over most of North America, flourishing in damp, disturbed ground along roads and ditches.
