Astragalus (Astragalus membranaceus), commonly known as Huang Qi, is a hardy perennial herb valued in traditional herbal gardens for its long taproots and delicate yellow blooms. This legume family plant enriches the soil with nitrogen while providing beauty and utility. Astragalus thrives in full sun and well-draining soil, making it suitable for herbal wellness gardens, borders, and naturalized landscapes. Once established, it returns year after year with minimal care.
