One of the few annual species that grows at high altitude, Fringed Gentian can be found coloring wet meadows and bogs when most other flowers are done blooming. It grows at 10,000 feet in my area and blooms in August. In the wild, it is of small stature - usually under 4 inches tall; however, in the garden, where it seeds around freely, it has attained a height of 18 to 24 inches with large, multiple blossoms.
