Summary
Hedysarum sulphurescens, commonly known as yellow sweetvetch, is a perennial herb native to alpine and subalpine zones, meadows, and open forests. It is often found in the mountainous regions of North America, including the Rocky Mountains and other ranges. This species typically grows to a height of 0.5 to 2 feet (15 to 60 cm) and spreads 0.5 to 1.5 feet (15 to 45 cm). Yellow sweetvetch has compound leaves with multiple leaflets and produces clusters of small, pea-like yellow flowers in the summer, which are moderately showy and attract pollinators.
Yellow sweetvetch is valued for its nitrogen-fixing ability, which can improve soil fertility, making it a beneficial addition to restoration projects and naturalistic plantings. It is also used in wildflower gardens for its attractive foliage and flowers. In cultivation, it prefers full sun to partial shade and requires well-drained soils. There are no major diseases or pests associated with this plant, but it may require protection from grazing if planted in areas with wildlife.CC BY-SA 4.0
