Astragalus scaphoides is a perennial herbaceous plant, with pinnate leaves. The pale yellow flowers open in May and are visited by several species of bumblebees and solitary bees, including species from the genera Osmia and Anthophora.
Plants can be found near Lemhi Pass on the Montana-Idaho border, and near Bannack State Park in Montana.
Plants tend to flower in alternate years,[4] similar to mast years in grasses and trees.
