Because their blue is true blue, bluer than the ocean, darker than the summer sky, almost like indigo. The family consists of more than 400 species which often hybridize among themselves. ROCKY DIAMOND BLUE HEART is a variety from Denmark, bred and found by Rune Nielsen in 2007. It was patented under PP21924 in 2011.

This variety was selected for a neat and very compact growth.Gentian is a slow growing, mat-forming perennial requiring zero maintenance. Plant it in humus-rich, reliably moist but well-drained soil in full sun or only partial shade. Autumn flowering species require slightly acid soil. Hardy to about -29°C (USDA zone 5).
