About
Astragalus canadensis is a perennial plant that can reach heights of up to 1.2 meters. Its foliage consists of 15 to 35 small, oval leaflets, each measuring approximately 3 centimeters in length. The plant produces clusters of flowers resembling peas, which range in color from white to a greenish-yellow. These flowers are arranged on spikes that can extend to 15 centimeters, emerging from the leaf axils at the tips of the branching stems.
