HydrangeasHellebore is one of the few perennials that bloom while the garden is still asleep — in December, February or even straight through the snow. Its cup- or rose-like flowers stay on the plant for weeks. Here are the main types of hellebore, how to plant and care for it, why it is dangerous (the plant is poisonous) and what to grow it with.
What is hellebore?
Hellebores (Helleborus) are a genus of about twenty species of herbaceous perennials in the buttercup family. Wild hellebores grow across Europe — from the Mediterranean to the Carpathians — and in Western Asia. The plant forms a dense clump of leathery, hand-shaped leaves and, in late winter or spring, produces stems with large nodding flowers.
An interesting detail: what look like petals are actually sepals. They don't fall after pollination but slowly turn green, which is why hellebores stay decorative for so long. The true petals have become small nectaries in the centre of the flower.
The plant has many common names: "Christmas rose" for H. niger, which can bloom around Christmas in Western Europe, and "Lenten rose" for the hybrids that flower in late winter. The scientific name is linked to Greek words for "to harm" and "food" — a hint at its toxicity.
Hellebore species and varieties
- Christmas rose (H. niger) — white or pinkish flowers, the earliest to bloom. "Niger" (black) refers to its dark roots.
- Lenten rose (H. × hybridus) — the largest group of garden varieties: white, cream, pink, burgundy, near-black, speckled and double flowers.
- Stinking hellebore (H. foetidus) — a tall evergreen with green, maroon-edged bells; the leaves only smell unpleasant when crushed.
- Purplish hellebore (H. purpurascens) — a wild species that grows in the Ukrainian Carpathians, among other places, with purple-green flowers.
- Corsican hellebore (H. argutifolius) — a large plant with toothed grey-green leaves and lime-green flowers.
Planting hellebores
- Position: partial shade under deciduous trees and shrubs — there's enough light for flowering in spring, and summer shade protects the leaves.
- Soil: loose, fertile, rich in organic matter and well-drained, neutral to slightly alkaline. Hellebores hate waterlogging.
- Timing: spring or early autumn (September to early October), so the roots establish before frost.
- How: dig a hole twice the size of the root ball, add compost and don't bury the crown. Space plants 30–45 cm apart.
Choose the spot carefully: mature hellebores dislike being moved but can thrive in one place for decades.
Hellebore care
- Watering — moderate, mainly in dry spells and during the first year.
- Mulch with compost or leaf mould in autumn to feed the plant and keep in moisture.
- Remove old leaves. On hybrid hellebores, cut off last year's leaves in late winter before the buds appear: the flowers become more visible and leaf spot is less likely.
- Feeding — a modest dose of balanced fertiliser or compost in spring.
- Propagation. Hellebores self-seed readily; seedlings flower in their second or third year. Named varieties are divided right after flowering.
Hellebores are very hardy. In hard frost the flower stems may flop, but they stand up again when it warms.
Caution: hellebore is poisonous
All parts of the plant, especially the roots, contain cardiac glycosides and other toxic compounds. Wear gloves, avoid planting it where small children play and make sure pets don't chew it. Hellebore was once used in folk medicine, but because of its toxicity self-treatment is dangerous. Learn more in our article on poisonous plants of Ukraine.
Hellebore legends
A Christian legend tells of a poor girl weeping by the manger in Bethlehem because she had no gift for the Christ Child; an angel touched the snowy ground and white flowers grew from her tears. A Greek myth describes the seer Melampus curing the daughters of King Proetus of Argos of madness with hellebore. And one modern (unproven) hypothesis links Alexander the Great's sudden death to hellebore poisoning.
What to plant with hellebores
Good companions are other early bloomers and shade-loving perennials: snowdrops, crocuses, primroses, scillas, ferns and hostas, which fill the space after the hellebores finish. For more ideas see our articles on early spring flowers and the first flowers of spring.
Hellebores can be cut for bouquets: mature flowers that have started forming seed pods last best. Young flowers are better floated in a wide bowl of water.
FAQ
When do hellebores bloom?
Depending on the species and weather, from December to April; in Ukraine most often from February to April.
Do hellebores need winter protection?
Established plants overwinter without cover; mulch young plants.
Why isn't my hellebore flowering?
Usually because of deep shade, recent transplanting or a young seedling.
