Description

Astragalus canadensis is a perennial herb that typically grows to a height of 30 to 90 centimeters. The plant has a robust, erect stem and pinnately compound leaves that are 10 to 20 centimeters long, with 15 to 31 leaflets. The leaflets are oblong to lanceolate in shape and have a smooth margin.

The flowers of Astragalus canadensis are creamy white to pale yellow and are arranged in dense, elongated racemes. Each flower is about 1 to 1.5 centimeters long. The blooming period is from June to August. The fruit is a legume pod that is 2 to 4 centimeters long, containing several seeds.

Habitat and Distribution

Ecological Importance

Astragalus canadensis plays a significant role in its ecosystem. As a member of the Fabaceae family, it is involved in nitrogen fixation, which enriches the soil and benefits other plants. The flowers are visited by various pollinators, including bees and butterflies, making it an important species for maintaining pollinator populations.

Uses

While Astragalus canadensis is not widely known for its medicinal uses, some Native American tribes have used it for various traditional remedies. The plant is also valued in restoration ecology for its ability to improve soil quality and support native plant communities.

Conservation Status

Astragalus canadensis is not currently listed as a threatened or endangered species. However, habitat loss due to agricultural expansion and urban development poses a potential threat to its populations in some areas.
