Also known as the Corsican hellebore, Helleborus argutifolius is an evergreen perennial grown for its bold, leathery, sharply toothed leaves and its clusters of pale yellow-green, cup-shaped flowers that open in the depths of winter when little else is in bloom.

Winter presence

The thick, blue-green foliage holds its color all year, giving structure to a shady border even in the cold months. As winter fades, nodding chartreuse cups appear and linger into early spring, a welcome sight for early pollinators.

Care tips

Plant it in dappled to deep shade with well-drained soil, and mulch in colder regions to protect the roots. It asks for very little once settled in.

Heads up: all parts of the green hellebore are toxic if eaten. Handle with care and keep it away from curious pets and children.
