Overview

Columbian Bitterroot (Lewisia columbiana) is a perennial forb or herb native to the Pacific Northwest of North America, including British Columbia and states like Idaho, Montana, Oregon, and Washington.

Known for its edible roots, which can be harvested and prepared in various ways, Columbian Bitterroot features distinctive pink or white flowers with a yellow center, setting it apart from other plants in the genus Lewisia. Its hardiness ranges from zones 4-8, making it adaptable to various climates within its native range. Cultivation requires well-draining, light (sandy) or medium soil and consistent moisture. For best results, ensure the soil drains well and keep it consistently moist. Propagation can be done through seeds or division of established plants. The edible parts are the roots, which can be harvested carefully to enjoy their culinary benefits.
