Helleborus viridis

Helleborus viridis, commonly called green hellebore, is a perennial flowering plant in the buttercup family, Ranunculaceae, native to Central and Western Europe, including England. All parts of the plant are poisonous.

The green hellebore was one of the many plants first described by Linnaeus in volume one of his 1753 tenth edition of his Species Plantarum. The species name is the Latin adjective viridis, "green". Two subspecies are recognised, subspecies viridis from Central Europe and the maritime Alps, and subspecies occidentalis from western Europe including England.
