Gillenia

Gillenia is a genus of two species of perennial herbs in the Rosaceae family. Common names for plants in this genus include: Bowman's root, indian-physic, American ipecac. This genus is endemic to dry open woods with acidic soils in eastern North America. Both plants are subshrubs with exposed semi-woody branches and serrated leaves; the larger lower leaves are divided into palmately arranged leaflets. Plants bloom in May, June, or July; blooms are composed of five slender white petals which are loosely arranged and typically appear slightly twisted and limp as if they were wilted. The flowers mature into small capsules. These plants are often planted as ornamentals and used medicinally as an herbal remedy.

The two similar species can be distinguished by their stipules. In G. stipulata, the stipules at the base of the leaves, which are round and deeply toothed, persist throughout the life of the plant. In Gillenia trifoliata the long slender stipules are quickly deciduous, this species also tends to have longer leaves and petals.

Gillenia trifoliata is an ornamental plant.
