Helleborus argutifolius

A perennial of the Ranunculaceae family, Helleborus argutifolius is native to Corsica and Sardinia, where it grows in open maquis, rocky undergrowth, and shaded garrigues, on calcareous or siliceous substrates, from sea level up to about 1,000 meters in altitude.

It is one of the most robust and architectural hellebores. It forms persistent bushy clumps 50 to 80 cm in height, borne by thick, upright stems that slightly lignify at the base with age. The leaves, trifoliate, are a shiny dark green on the upper side, with strongly and regularly toothed margins in spiny teeth, a characteristic that earned it its epithet: argutifolius literally means "with sharp-toothed leaves". This leathery and persistent foliage is in itself a striking presence all year round.

The flowers, gathered in large terminal corymbs, are cup-shaped, from pale green to bright green-yellow, with many stamens clearly visible at their center. The entire plant is toxic, like the whole genus.

In its natural environment, its flowering extends from February to April. In cultivation under a temperate climate, it often occurs as early as January-February, making it one of the earliest blooms in the garden.

It tolerates some summer drought once established, prefers well-drained, calcareous or neutral soil, enriched with humus, in partial shade or light cover. Perfectly hardy down to about -15 °C.
