Gentiana is a genus of flowering plants belonging to the Gentian family (Gentianaceae).
This is a cosmopolitan genus, occurring in alpine habitats of temperate regions of Asia, Europe and the Americas. Some species also occur in northwest Africa, eastern Australia and New Zealand. They consist of annual, biennial and perennial plants. Some are evergreen, others are not.
Many gentians are difficult to grow outside their wild habitat, but several species are available in cultivation. Gentians are fully hardy and like full sun or partial shade, and neutral to acid soil that is rich in humus and well drained. They are popular in rock gardens.
According to Pliny the Elder, Gentian is an eponym of Gentius (180-168 BC), the King of Illyria, said to have discovered its healing properties. Some species are of medicinal use and their roots were harvested for the manufacture of tonic liquor, for instance in France "Suze" or similar liquors. Gentian is also used as a flavouring, for example in bitters, and the soft drink "Moxie" which contains "Gentian Root Extractives".
