Trifolium barbigerum is a species of clover known by the common name bearded clover. It is native to Oregon and northern and central California, where it grows in many types of habitat, including disturbed and cultivated areas. It is an annual herb growing decumbent to erect in form and hairy to hairless in texture. The leaves are divided into oval leaflets up to 2.5 centimeters long, sometimes having notches at the tips. The stipules on the leaves are large and variable in shape. The inflorescence is a head of flowers up to 2.5 centimeters wide. The flowers are held in a bowl-shaped involucre of bracts with toothed edges. Each flower has a calyx of sepals narrowing into one or more bristles which are coated with long hairs. Within each calyx is the flower corolla which may be pinkish purple, white, or bicolored purple and white.
