This tap-rooted perennial is native to China, super cold-hardy (to zone 6) and drought tolerant. It loves warm, well-drained soil and produces yellow pea-like flowers in mid-summer. Sow seed late spring after last frost.
Astragalus is a legume, meaning that it is related to peas, clover, and mimosa. Legumes are known to improve soil quality by establishing a symbiotic relationship with nitrogen-fixing bacteria that draw atmospheric nitrogen from the air and make it readily available to the roots of other plants.
