Hellebore refers to flowering plants in the genus Helleborus, a group of perennial plants in the buttercup family (Ranunculaceae). They are native to Europe and Asia and are valued in gardens for winter to early-spring blooms, evergreen foliage in many species, and shade tolerance. All parts of the plant are toxic and can cause poisoning if ingested.

Description

Hellebores are herbaceous perennial flowering plants, often with nodding or cup-shaped blooms and leathery, dark green foliage. Depending on species and cultivar, flowers may be white, pink, purple, green, burgundy, or bicoloured.

Taxonomy and distribution

Hellebores are members of the family Ranunculaceae and the genus Helleborus. They are native to Eurasia, with species concentrated in Europe and western Asia, especially around the Mediterranean region.

Garden use

Hellebores are widely grown as ornamental plants because they flower when little else is in bloom and are often tolerant of shade. They are used in woodland and winter gardens and are commonly described as long-lived perennials.

Toxicity and folklore

Hellebores contain toxic compounds, and ingestion can be harmful to people and animals. The plants also have a long history in European folklore and traditional medicine, though modern sources emphasize their poisonous nature.

  • Hellebores belong to the genus Helleborus in the buttercup family.
  • The genus includes about 20 species native to Europe and Asia.
