Description: 

Herbaceous, cool-season, reseeding winter annual legume. Mostly upright stems grow to 3-4 feet, are glabrous (not hairy), hollow, smooth, and often purple. Large conical flower head has white to pink flowers opening from bottom to top, turning brown when mature. Palmately trifoliolate, arrow-shaped leaves have a characteristic large, white V mark. Stipules are white, long, narrow, and pointed, with prominent veins. Deep tap root can penetrate up to 4.5 feet. Seeds are about twice the size of white clover, with 400,000 per lb. Nearly 70% are hardseeded, thus, seed requires scarification for satisfactory germination.
