Helleborus lividus (blue-grey hellebore) — Clump-forming, mounded

Overview

Helleborus lividus is a clump-forming, mounded perennial in the genus Helleborus, part of the Ranunculaceae family, with evergreen or semi-evergreen; leathery, palmately divided, dark green foliage. It typically grows around 0.45 metres tall. Helleborus lividus grows best in partial shade; tolerates full sun in reliably moist soil, and tolerates fertile heavy loam or clay with plenty of humus soils and neutral to alkaline pH. Its UK hardiness is rated H6-H7. It is native to Balearics.

About

Helleborus lividus is a clump-forming, mounded perennial in the Ranunculaceae with leathery, palmately divided dark green leaves and winter flowering. It grows to about 0.45 metres and flowers from January to April. It prefers neutral to alkaline, moisture-retentive heavy loam or clay in a sheltered, part-shade position. Wear gloves when handling as the sap can irritate and the plant is harmful if eaten.

About the genus

Commonly known as hellebores, the Eurasian genus Helleborus consists of approximately 20 species of herbaceous or evergreen perennial flowering plants in the family Ranunculaceae, within which it gave its name to the tribe of Helleboreae. Many hellebore species are poisonous.

In the garden

Helleborus lividus originates from the Balearic Islands and belongs to the genus Helleborus within the Ranunculaceae. The plant forms a low, mounded clump of leathery, palmately divided leaves and produces flowers in the winter months, specifically from January to April, providing structural evergreen foliage through colder seasons. Plant it where it receives partial shade; it will tolerate full sun only if the soil remains reliably moist. Soils should be fertile heavy loam or clay enriched with humus, neutral to alkaline in reaction, and kept moist but well drained. Position the plant on a north, east or west facing aspect and give it a sheltered exposure to reduce stress on leaves and blooms. It is classified H6–H7 (very hardy to fully hardy), reflecting good cold tolerance. At around 0.45 metres tall, Helleborus lividus suits borders and sheltered, semi-shady spots where evergreen foliage is useful through winter. Keep an eye on soil moisture in sunnier exposures and avoid free-draining, dry sites. Take care when pruning or dividing: the sap can irritate skin and the plant is harmful if eaten, so use gloves and protective equipment when handling.

Care notes

Pruning and caring for Helleborus lividus

Cultivation: Give them a cool, humus-rich root run under deciduous shrubs, where they get spring light and summer shade. They dislike being moved, so plant well and then leave alone. The single most useful job is removing the old leaves of the hybrid hellebores in midwinter: it exposes flowers that would otherwise be hidden, and strips out the foliage that carries leaf spot.
Pruning: Cut away the previous season's leaves of stemless kinds as the flower buds emerge in midwinter. On stemmed species such as H. foetidus and H. argutifolius, remove flowered stems at the base once they fade.
Propagation: Divide established clumps after flowering, though they re-establish slowly. Seed sown fresh germinates readily and self-sown seedlings are plentiful, but hybrids will vary from the parent.
Pest resistance: Slugs and snails damage emerging buds, and aphids gather on flower stems in spring.
Disease resistance: Hellebore leaf spot is common and disfiguring, and removing old foliage in winter is the main control. Hellebore black death, a virus, causes distorted blackened growth and affected plants must be destroyed.
