Canadian Milkvetch: An Unassuming Native That Feeds Bees & Birds

Walking local prairies, I look for plants thriving in diverse conditions — if they make it there, they'll handle my garden. Canadian milkvetch (Astragalus canadensis) isn't showy, but it grows on you: ferny foliage, unique summer blooms, and a pollinator/seed buffet for wildlife.

Caution: All Astragalus parts are toxic if ingested.
