In the garden

Actaea alba is a herbaceous perennial from Eastern North America in the buttercup family (Ranunculaceae). It is adapted to shaded, sheltered woodlands and will perform where soils stay moist and are rich in organic matter. It flowers July to September, providing mid-to-late summer interest where a shady planting is required. Give plants partial shade or full shade on a north, east or west aspect and avoid exposed sites; sheltered exposure is recommended. Soil should be moist, well drained and high in humus, with an acidic to neutral reaction. Mulching with leaf mould or well-rotted compost helps retain moisture and supports the humus-rich conditions the species prefers. In the UK garden use Actaea alba in a woodland border, beneath open-canopied trees, or for naturalising beneath shrubs where other shade perennials are grown. Its fully hardy rating (H7) means it tolerates typical UK winters when sited out of prevailing wind. Exercise care with siting around children and dogs, because all parts are toxic if ingested; place specimens away from paths and play areas to reduce the risk of accidental ingestion.
