Boreal sweetvetch (Hedysarum boreale), also called northern hedysarum, is a perennial plant in the legume family that typically grows up to 80 cm tall. It forms dense clumps of upright stems bearing numerous small, medium-green leaves arranged alternately along the stem. In summer, it is covered with clusters of pinkish-purple to deep purple flowers that are highly nectar-producing and attract bees and other pollinators. After flowering, it produces small, flat, segmented pods. Boreal sweetvetch naturally grows in dry prairies, rocky slopes, and gravelly or sandy soils across the temperate regions of Canada and the western United States. Once established, it is drought tolerant and thrives in sunny environments.

Ecological roles
Boreal sweetvetch plays an important role in dry and open ecosystems. Its deep roots help stabilize the soil and prevent erosion, while its flowers are a key resource for wild bees and bumblebees. Thanks to its ability to fix atmospheric nitrogen, it improves soil fertility and supports the regeneration of other native plants. It is often used in ecological restoration projects to re-establish vegetation cover in prairies and disturbed areas.

Growing Notes | Seeds - Boreal Sweetvetch

Boreal sweetvetch grows in full sun and prefers well-drained soils. It tolerates drought well once established.

The seeds require scarification by soaking to germinate.
Simply soak the seeds in hot water for 24 hours to soften the seed coat and promote absorption.
