Bowman's root, Indian physic
Rosaceae (Rose Family)
Synonym(s): Porteranthus trifoliatus
USDA Symbol: GITR6
This loose, informal, slender perennial, grows 2-3 ft. tall from a woody rootstock. One or more stems arise from each crown. Leaf blades are divided into three, narrow, toothed lobes. An erect plant bearing white or pinkish flowers with narrow petals and almost stalkless, 3-parted leaves. The whitish flowers have five narrow petals and are borne in loose panicles. Attractive red calyxes persist after the petals fall.
The five petals of this plant project somewhat irregularly. The dried and powdered root was used by Native Americans as a laxative and emetic, hence the common names. A southern and western relative, American Ipecac (G. stipulata), found from Kansas, Michigan, and New York south to Georgia and Texas, has large, sharply toothed or jagged stipules.
