Alpine sweetvetch
Hedysarum alpinum
Alpine sweetvetch is a hardy boreal and alpine perennial legume that prefers cool climates and well-drained, slightly sandy or loamy soils. It tolerates partial shade but blooms most prolifically with several hours of sunlight; water regularly during the growing season while avoiding waterlogged conditions. Known for its edible roots (famously consumed by Indigenous peoples and described by explorers), it also enriches soil by fixing atmospheric nitrogen.
