Gillenia trifoliata – Bowman’s Root; Indian Physic

General Information: A tall, slender perennial which blooms in early summer in the Northeast. A profusion of delicate star-shaped white or pink flowers adorn the thin red branches each June. This unique perennial fills tough sites with three-season interest. A versatile plant that succeeds in most moist soils and a variety of lighting conditions. The tall woody stalks attract attention even after the blooms have fallen, as the red flower support structures (calyxes) persist. In the fall, vibrant red foliage adds an end-of-season burst of color. The common name for the plant, “Indian Physic,” refers to the medicinal attributes of the plant that were utilized by Indigenous North American Peoples.

Cultivation Details: This plant is susceptible to Slug and Snail damage and should be monitored when young. The stems of this plant can also fall over in very wet or windy conditions and may require staking. The cold hardiness limit of this species is reported to be -4 °F, however we suspect they may tolerate lower temperatures as they are reportedly found in Jefferson and Lewis Counties in New York State, areas which can see winter extremes of -20°F. For optimal results, plant in a sheltered south or east-facing location, especially in Zones 5 and 6 where the cold is a concern. Consider planting Bowman’s Root in a woodland garden, along field or forest margins, as a foundation planting, for rewilding, or as a specimen. They succeed in most ordinary garden soils, especially weed-free and well-mulched ares.

Growing Requirements: Prefers part sun to nearly full shade. Tolerates nearly full sun if soil moisture and protection from the hottest midday sun is available. Requires moist, well-drained soils. Suitable for mildly acidic and neutral soils. Does not tolerate alkaline soils.
