Actaea simplex var. atropurpurea

Germination

Sow in a cold frame in autumn or sow indoors at any time. Outside, surface sow onto moist well-drained seed compost. Place in a cold frame, allow natural winter cold to offer ideal conditions for germination to occur as the weather warms in spring. Indoors, surface sow onto moist, well-drained seed compost, do not cover seed but press gently into the soil. Ideal temp. 22°C for 6 weeks then cold stratify. Move to 4°C for 6-8 weeks then return to warmth, 10°C, for germination. Germination takes 1-12 months and will usually occur in spring regardless of sowing time.. Transplant seedlings when large enough to handle to 8cm pots and grow on. Acclimatise and plant out after danger of frost has passed.

Growing

Prefers a cool, moist soil which has been enriched with organic matter. Water thoroughly in dry weather. Requires little attention.

Cultivation

Cut back plant after flowering ceases. Large established clumps can be divided in spring.
