Helleborus — 6 species

Helleborus is a genus of tough, clump-forming perennials celebrated for blooming in late winter to early spring, often pushing through snow. Plants such as Helleborus niger (Christmas Rose) and Helleborus × hybridus (Lenten Rose) thrive in partial to dappled shade — ideally beneath deciduous trees — with moisture-retentive, well-drained, slightly alkaline soil. Water regularly during active growth in spring and autumn; established plants tolerate drought but appreciate supplemental water in summer. All parts of Helleborus are toxic to cats, dogs, and horses — keep well away from pets.
