The Story
Plant Bio
Actaea simplex, Kamchatka bugbane, is an upright clumping perennial from eastern Asia, reaching about five feet in flower. Deeply cut compound foliage sits on wiry brownish-purple stems, and in late summer and autumn slender bottlebrush spikes of small fragrant white flowers rise well above the leaves.
It flowers in autumn, later than almost any other shade perennial, and the spikes are strongly scented — worth siting near a path for that alone. The dark-leaved cultivars need morning sun to hold their colour and scorch in afternoon heat. All parts are toxic, and the berries most of all, so keep it away from small children.

Planting
How to Grow
- Plant in dappled or partial shade, sheltered from wind.
- Give it consistently moist, humus-rich soil.
- Site dark-leaved forms out of hot afternoon sun.
- Water through dry spells; it will not tolerate drought.
- Stake tall stems in exposed positions.
- Leave it undisturbed; it dislikes being moved.
Pro Tip
It flowers on five-foot stems in autumn, so plant it where those spikes will not be flattened by the first wind of the season.
