It is endemic to Wyoming in the United States, where it is known only from the Laramie Mountains.[1][2][3] This rhizomatous perennial herb produces stems up to 25 centimeters long. The leaves are compound, divided into leaflets. The nodding flowers have greenish white[1] or lavender[3] sepals up to 1.5 centimeters in length. The cream-colored[1] to lavender[3] petals are up to 1.2 centimeters long and have thick, hooked spurs. The fruit is a follicle up to 1.4 centimeters long.[1] This plant is limited to one mountain range in Albany and Converse Counties in Wyoming.[2][3] Many occurrences are within Medicine Bow National Forest, and the others are on land managed by the Bureau of Land Management and on privately owned land. Occurrences are small, most containing fewer than 100 individuals.[3] The plant grows on large rock outcrops in pockets of soil and rock cracks. The outcrops are surrounded by forest habitat and sometimes sagebrush and grassland. It grows in shady spots in all aspects. Associated species include fragile fern (Cystopteris fragilis), little-flowered alumroot (Heuchera parvifolia), glandular oceanspray (Holodiscus dumosus), mountain ninebark (Physocarpus monogynus), Brandegee's Jacob's ladder (Polemonium brandegeei), bigflower cinquefoil (Potentilla fissa), red raspberry (Rubus idaeus), Idaho ragwort (Senecio rapifolius), and Rocky Mountain woodsia (Woodsia scopulina).[3] There are no major threats to the species because it occurs in remote, rugged habitat.[2] {{Commonscat|Aquilegia laramiensis}}References1. ^1 2 3 Aquilegia laramiensis.
