Astragalus canadensis (Canada milkvetch) is a long-lived native perennial found across much of Canada, including Ontario. It typically grows 2-3.5 feet tall, forming upright clumps with pinnate leaves and dense spikes of creamy white to pale yellow flowers in early to mid-summer.

As a member of the pea family, it fixes nitrogen in the soil, improving soil fertility and supporting pollinators such as native bees. It is most often found in prairies, open woodlands, and along roadsides, preferring full sun to light shade and well-drained soils.

While not considered aggressive, it can spread by seed in suitable conditions, making it appropriate for larger meadow plantings, restoration sites, or naturalized gardens rather than tightly managed beds. Its elongated seed pods that turn papery with age are a distinguishing feature later in the season.
