About
Aquilegia coerulea, commonly called the Colorado columbine, Rocky Mountain columbine, or blue columbine, is a species of flowering plant in the buttercup family, native to the Rocky Mountains in the western United States. It is a moderate sized wildflower that grows in mountainous areas from the foothills to above timberline. The flowers are mainly pollinated by bumblebees and several species of hawkmoths. The species has been the state flower of Colorado since 1899 and with its large, showy flowers is a frequent garden plant and used in the breeding of columbine hybrids. The botanical name coerulea (or caerulea) means 'sky blue'.
Where it grows
Colorado columbine is native to the Rocky Mountains from northern New Mexico to southern Montana. It grows in all of the mountainous western half of Colorado and Wyoming. Additionally it grows in every county of Utah, parts of Nevada, and northern Arizona. It is listed by the USDA as growing in Idaho and South Dakota, but without county level distributions. The species was reported to grow in the Caribou–Targhee National Forest in eastern Idaho in 1973. Though the geographic center of the range is in eastern Utah, the greatest number of plants is found in the mountains of north central Colorado.
