distribution_en:

description_en: Genus of 200 or more species of annuals, often rhizomatous or tap-rooted herbaceous perennials, semi-evergreen subshrubs, and usually evergreen shrubs. They are found throughout the world, except in Australasia, and occur in moist woodland, meadows, or at streamsides, often in mountainous regions; the alpine species grow in scree or rock crevices. The opposite leaves are often aromatic, but not always pleasantly so; they are generally simple, although the non-shrubby species often produce pinnate or pinnatifid stem leaves as well as basal rosettes of simple leaves. The small, unisexual or bisexual, salverform flowers are pink to lavender-pink, white, or yellow, and are borne in terminal, panicle- or corymb-like cymes in summer. The few species in cultivation are herbaceous perennials, grown for their attractive flowers. Valerians are suitable for growing in an informal, cottage-style garden, herbaceous border, or herb garden, or for naturalizing in a wild garden.
