Скачать или смотреть A Prairie Moment - Canada Milk Vetch (Astragalus canadensis)

Although not a colorful plant, the Canada Milk Vetch (Astragalus canadensis) can make up for that in its structure, form, and pollinator value. We see plenty of hummingbirds, and butterflies on this plant, and this species is also one of the host plants for the Clouded Sulphur butterfly.

We find it quite happy on our gravel slopes and in the wetter bottom mesic areas. This is a Legume and most legume species contribute beneficial bacteria called rhizobia on their roots. Strains of this bacterium aids in the fixation of atmospheric nitrogen - improving long-term health of native plant communities.
