25 Hedysarum boreale Seeds Utah Sweetvetch Native Wildflower Pink Purple Flowers

Hedysarum boreale, commonly known as Utah Sweetvetch, is a hardy native wildflower of the American West, valued for its clumping habit and cheerful pea-like blooms in shades of pink and purple. It brings a natural, meadow-style look to rock gardens, pollinator plantings, and low-water landscapes, and its deep-rooted nature helps it settle into sunny, open sites.

This native perennial works well in mixed borders, native plant gardens, and informal wildflower areas, where its summer flowers and fine-textured foliage add soft color and structure. A nitrogen-fixing species, it grows best in lean, well-drained soils and tolerates dry conditions once established, making it a practical choice for water-wise and habitat-friendly plantings.
