Gentians are ideal for the rockery garden (alpinum) for well drained spots with plenty of sunlight. Need very little care and are best left alone for years. All have very attractive bright colored flowers in white, blue to purplish (only one yellow) shades.
Sow in autumn to early spring on top of any rocky or sandy soil with only few organic parts. Do not cover seeds, keep post in full sun, always water from beneath. Pot-culture for one year, first flowers in their third year (Gentiana lutea after five years).
All are USDA Climate Zone 6.
