Although Astragalus alpinus is small and individual flowers are tiny, it is still easy to spot because it is often found in large colonies and there are numerous colorful flowers on each stalk.  Astragalus alpinus flowers range through shades of purple combined with white.

Welsh indicates that this circumpolar species, "is perhaps the most widely distributed species of Astragalus in existence. In Utah it is rare, but in much of North America it is the most common species in the genus".

Linnaeus named this species in 1753 from a specimen he collected in Lapland in 1732.
