Description
editIt is a perennial plant, growing up to a height of 10 centimetres (3.9 in) tall and forming a mat up to 50 centimetres (20 in) wide.[9] The leaves, which can be lanceolate, elliptical or obovate,[7] are evergreen, 2–3.5 cm long, in a basal rosette, forming clumps. The trumpet-shaped terminal flowers are blue with olive-green spotted longitudinal throats.[9] 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.
Horticulture
editThis plant, like others of its genus, is valued in cultivation for the unusually pure intense blue of its blooms. It has gained the Royal Horticultural Society's Award of Garden Merit.[9][10]
Etymology
editThe Latin specific epithet acaulis means "short-stemmed".[11]
Taxonomy
editThe closely related Gentiana clusii, often called by the same common name as this species, differs in its preference for limy (alkaline) soils. It also has shorter leaves and the flowers have no olive-green stripes.
Phylogeny
editPhylogenetic research suggests G. acaulis is sister to a clade containing 4 other Gentiana species: G. verna, G. bavarica, G. nivalis, and G. utriculosa.[12]
