Astragalus Drummondii Seeds – 30 Woolly Milkvetch Native Prairie Legume

Astragalus drummondii, commonly known as Woolly Milkvetch, is a native prairie legume prized for its silvery, woolly foliage and delicate cream-to-purple wildflowers. This drought-tolerant perennial adds texture and ecological value to native plant gardens, pollinator plantings, and xeriscapes. Its low-maintenance nature and attractive blooms make it a standout choice for meadow restorations and water-wise landscapes.

Woolly Milkvetch typically blooms in late spring to early summer, producing small pea-like flowers that attract bees and other beneficial insects. The plant's fuzzy gray-green leaves provide season-long interest even when not in bloom. As a legume, it can help improve soil fertility by fixing nitrogen, making it a useful companion in prairie and wildflower mixes.

Planting & Care

Sow Astragalus drummondii seeds in a well-drained seed-starting mix, barely covering them with soil as light may aid germination. Keep the medium consistently moist but not waterlogged. Germination can be improved by scarifying the seed coat or soaking seeds in warm water for 12-24 hours before sowing. Once seedlings have several true leaves, transplant them into individual pots or directly into the garden after the last frost.

Choose a sunny location with sandy or rocky, well-drained soil. Water regularly during the first growing season to help establish a deep root system, then reduce watering as plants become drought tolerant. Avoid overly rich or poorly drained soils, which can cause root rot. Deadhead spent flowers to encourage continued bloom, though allowing some seed heads to mature can support self-seeding and provide food for wildlife.
