Bowman's Root

Two closely related species of rhizomatous woodland perennials belong to this eastern N American genus. Gillenia trifoliata is widely grown as an ornamental for its elegant display of white flowers. Gillenia stipulata, similar in both properties and appearance, is found farther south in the wild. They are distinguished mainly by the number of leaflets: three in the case of G. trifoliata and five in the case of G. stipulata (the two extra ones are actually stipules). Gillenia trifoliata was known to many N American tribes and was adopted by the early colonists. It was listed in the U.S. Pharmacopoeia (1820-82). The same common names are generally shared between G. trifoliata and G. stipulata.

Erect herbaceous perennial with branched, red-green stalks, and trifoliate, deeply toothed and veined leaves, to 8cm (3in) long. White or pink-tinged flowers, 1-2cm (3/8-¾:in) across, with narrow petals and red-green calyces, are borne in loose panicles in late spring and summer.
