25 Seeds Utah Sweetvetch Hedysarum boreale Native Perennial Nitrogen Fixer

Utah Sweetvetch is a hardy native perennial legume valued for its delicate pink-purple pea-like flowers and ferny green foliage. Blooming through late spring and early summer, it brings a soft, natural texture to wildflower meadows, rock gardens, and low-water landscape plantings.
Utah Sweetvetch works well in native plant gardens, pollinator borders, and xeriscape designs, where its clumping habit and taproot make it a long-lived, low-maintenance choice. It pairs nicely with other drought-tolerant perennials and grasses, and its fine texture contrasts well against broader leaves.
