Black false hellebore

Veratrum nigrum

''Veratrum nigrum'' is a widespread Eurasian species of perennial flower of 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. For example, Lucretius and Pliny the Elder both knew of its medicinal emetic as well as deadly toxic properties.
