Trumpet gentian

The blue of the mountains

The trumpet or stemless gentian is one of the most loved and recognisable mountain plants. It forms a small rosette of basal leaves pressed to the ground, from which spring large solitary trumpet- or chalice-shaped flowers of a deep, intense blue that few other flowers reach in nature. The name 'acaulis' means 'stemless': the flowers seem to rest almost directly on the cushion of leaves.

Habitat and distribution

It is native to the mountains of central and southern Europe, from Spain to the Balkans, and grows especially in the Alps and Pyrenees, between about 800 and 3,000 metres altitude. It favours pastures, alpine meadows and stony, acidic, siliceous soils, where it flowers in spring and early summer, often just after the snow melts.

Cultivation

It is grown in rock and alpine gardens for its spectacular flowers, but it is not always easy: it wants full sun, a cool but perfectly drained, acidic soil, and cool temperatures. It resents lowland summer heat and waterlogging. In cultivation it does best when the high-altitude conditions it comes from are recreated.

Curiosities

The colour 'gentian blue' entered everyday language thanks to these flowers. Gentians have a long tradition in herbalism (especially the great yellow gentian, with its bitter roots), while the trumpet gentian is prized above all as an ornamental icon of alpine flora.

Conservation

The species is Least Concern, but in many alpine regions it is protected: picking the flowers is banned or regulated. Admiring it on mountain meadows without picking it is the best way to help preserve it.
