Veratrum nigrum, the black false hellebore, is a widespread Eurasian species of perennial flowering plant in the family Melanthiaceae. Despite its common name, V. nigrum is not closely related to the true hellebores, nor does it resemble them. The plant was widely known even in ancient times. It is native to Southern Asia, Albania, Altay, Amur, Austria and other regions. Mature plants reach roughly 1-1.5 metres tall and 0.1-0.5 metres wide, carrying deciduous foliage. In the garden it prefers full sun and partial shade and most soil types. It tolerates acid and neutral soils, moist but well-drained conditions and south-facing, west-facing and east-facing aspects.
