Helleborus Niger - Horticulture

Horticulture

The plant is a traditional cottage garden favourite, because it flowers in the depths of winter; large-flowered cultivars are available, as are pink-flowered and double-flowered selections. It has been awarded an Award of Garden Merit (AGM) H4 (hardy throughout the British Isles) by the Royal Horticultural Society, as has one of its hybrids (see below).

It can be difficult to grow well; acid soil is unsuitable, as are poor, dry conditions and full sun. Moist, humus-rich, alkaline soil in dappled shade is preferable. Leaf-mould can be dug in to improve heavy clay or light, sandy soils; lime can be added to 'sweeten' acid soils.
