Veratrum nigrum, Black false hellebore

Veratrum nigrum (common name black false hellebore) 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 (ca. 99 BCE – ca. 55 BCE) and Pliny the Elder (23 AD – August 25, 79) both knew of its medicinal emetic as well as deadly toxic properties.
