This is a cosmopolitan genus, occurring in alpine habitats of temperate regions of Asia, Europe and the Americas.
True sapphire blue upward-facing 2" flowers mingle with the emerald green foliage producing long-blooming garden treasures. Flowers sparkle with the morning dew. Prolific flowering occurs up and down the stems on each node from midsummer into early fall. The smooth, mid-green, lance-shaped leaves form a nice sized clump that is perfectly proportioned for the middle of the flower border. Compact and well-branched habit. A charming addition to the hard to find "blues" in perennials. Easier to grow than most Gentians, this beauty sends up a multitude of flowers, often blooming right into fall. Prefers full sun to part shade, but should be protected from the afternoon sun in regions with hot, humid summers. Well-drained soil with average moisture.
