Helleborus argutifolius, commonly known as the Corsican Hellebore, is native to the Corsican Islands. Extreme care must be taken when handling this plant as every part is poisonous and it can elicit severe allergic reactions and these reactions can present even if it has been handled without complication before. Helleborus argutifolius is synonymous with Helleborus corsicus.

The etymological root of the binomial name Helleborus is the classical name of Helliborus niger. Argutifolius is derived from the Latin meaning ‘with sharply-pointed leaves’.

Helleborus argutifolius is useful to the landscape architect in a naturalistic woodland setting with dappled shade for its attractive winter flowers and as an effective evergreen ground cover. It is fully frost hardy.
