Prairie Rosinweed, Prairie Dock, Prairie Burdock, Turpentine, Turpentine Weed
Noted for its spectacular foliage and profuse blooms, Silphium terebinthinaceum (Prairie Dock) is a tall herbaceous perennial forming a basal rosette of huge, oblong to heart-shaped, dark green leaves, up to 2 ft. long (60 cm). From midsummer to mid-fall, sturdy, upright, branching stems bear a profusion of bright yellow, daisy-like flowers, 3 in. across (7 cm). The flowers resemble small sunflowers with their yellow rays surrounding a yellow central disk. The blossoms are followed by large seeds that are favored by birds. This species is also commonly called Prairie Rosinweed because its stems exude a gummy, bitter resin when broken or cut. Prairie Dock is a great choice for prairies or other natural plantings.
