Canada Milkvetch
Astragalus canadensis
Canada Milkvetch stands out in meadows and wildflower gardens with its showy racemes of white to pale yellow flowers that bloom throughout the summer. This plant not only adds aesthetic value but also plays a crucial ecological role by fixing nitrogen in the soil, which improves soil fertility. Its deep root system helps to stabilize the soil and provides a habitat for beneficial insects. After flowering, the plant produces interesting seed pods that are attractive to various bird species.

Maintenance Tips
- Drought-tolerant once established; water deeply but infrequently after first planting to encourage strong root growth.
- Little to no pruning required; remove old flower stems in late fall or early spring if necessary for aesthetics.
- Prefers well-drained soils but can adapt to a range of soil types, including poor soils.
- Allow seedlings to naturalize in restoration projects or remove them to control spread in more formal garden settings.
