Native to the European Alps, this spring-flowering Gentian is a much-loved alpine plant that is not always the easiest to grow.
It forms a low, slow-spreading carpet of pointed green leaves, bearing large upfacing funnel-shaped flowers in the most amazing shade of deep, true blue.
Requires a rich, acidic and evenly moist soil, and has a distinct preference for cool-summer climates. Often performs best in a rock garden situation, where the roots can stay cool and moist. Protect from hot afternoon sun.
Consider this plant to be a challenge for the more advanced gardener, though beginner’s luck is a distinct possibility!
