Helleborus argutifolius
This species is the Corsican hellebore with bold, leathery leaves. Plants make larger clumps with many lime green flowers in late winter. It prefers partial shade but tolerates brighter light where summers are cool. It grows best in well drained soil and mild winter regions. It is less cold hardy than the typical hybrid Lenten rose.
