description_en: Genus of about 400 species of hardy annuals, biennials, and deciduous, semi-evergreen, and evergreen perennials. They are widely distributed throughout temperate zones, most occurring in alpine habitats, with some, mainly North American and Japanese species, in woodland. They bear large, usually trumpet-shaped, sometimes bell- or almost urn-shaped flowers from spring to autumn, mainly in shades of intense blue, but also in white, yellow, or occasionally red. Leaves are simple and borne along the stems in opposite pairs or whorls, or produced in basal rosettes. Many autumn-flowering species have overwintering rosettes and are classed as semi-evergreen; the flowered stems die back each year to the rosettes. Small species, to about 15cm (6in) high, are suitable for a rock garden or peat terrace; more robust species are suitable for borders. Woodland natives, like G. asclepiadea, thrive in partially shaded sites, associating well with ferns and grasses. G. sceptrum is suitable for a bog garden; G. lutea is effective beside water. Autumn-flowering gentians associate well with small, late-flowering bulbs.
