Achillea ptarmica, 'The Pearl'

Germination

Sow indoors. Surface sow onto moist well-drained seed compost. Do not cover seeds as light aids germination. Propagate or place somewhere warm 18-22°C. Water from the base of tray only. Keep moist but not wet. Germination takes 7-14 days. When seedlings have 2 true leaves prick out to 8cm pots and grow on. Acclimatise and plant out once danger of frost has passed with 100cm spacing.

Growing

Prefers a more moist soil than other Achilleas in partial shade. Requires little attention.

Cultivation
