Ciminalis acaulis |
Gentiana acaulis (often called "stemless gentian" although that may equally apply to G. clusii) is a small gentian native to central and southern Europe from Spain east to the Balkans, growing especially in mountainous regions, such as the Alps, Cevennes and the Pyrenees, at heights of 800 to 3,000 m.
It is a perennial plant, growing on acidic soils. Its height is 2 cm and spread is 10 cm or more. The leaves are evergreen, 2-3.5 cm long, in a basal rosette, forming clumps. The trumpet-shaped terminal flowers have a blue colour with olive-green spotted longitudinal throats. They grow on a very short peduncle, 3-6 cm long. The flower stem is often without leaves, or has 1 or 2 pairs of leaves.
It likes full sun, is fully hardy and flowers in late spring and summer.
The closely related Gentiana clusii differs in growing on limy soils. It has shorter leaves and the flowers have no olive-green stripes.
