The herbaceous perennial plant Gentiana calycosa is a species of gentian known by the common names Rainier pleated gentian and Mountain bog gentian. It is native to the mid-elevation mountains of the western United States and Canada from the Sierra Nevada of California to the Canadian Cascades. The flower is a funnel-shaped cup opening into a five-petaled face 3 to 5 centimeters (1.2 to 2.0 in) wide, in shades of deep blue to purple. The plant has hardy, thick green leaves on the thin red stems from which the flowers are borne. Like other gentians, G. calycosa is an attractive mountain wildflower good for use in alpine gardens.
