White sweetvetch
Hedysarum sulphurescens
White sweetvetch is a hardy native legume perennial from the Rocky Mountain and Great Basin regions, well-suited to open meadows and mountain garden settings. It grows best in well-drained, moderately fertile soil with partial to full sun and benefits from infrequent but deep watering. As a nitrogen-fixing legume, it naturally enriches the soil and provides attractive white to pale yellow flower spikes for pollinators.
