How to grow anemone
Overview
Anemone coronaria is a tuberous perennial grown from corms for its vivid, poppy-like flowers in late winter to spring. It provides a burst of seasonal colour and requires a distinct dry summer dormancy to thrive.
Varieties
- Mona Lisa — Large, double flowers in mixed colours; reliable in temperate gardens.
- De Caen — Single, poppy-like blooms in bright red, blue, pink, and white; the classic cut-flower strain.
- St Brigid — Semi-double to double flowers with a ruffled look; popular for garden colour.
Soil Preparation
Prefers a neutral to slightly alkaline soil (pH 6.5–7.5) with sharp drainage. Amend heavy clay with coarse sand or grit. Incorporate well-rotted compost at 2–3 cm depth before planting, but avoid fresh manure which can rot corms.
Growing Guide
Plant corms 5–8 cm deep and 10–15 cm apart in well-drained soil. Soak corms in tepid water for 2–4 hours before planting to rehydrate. Position in full sun with steady moisture during growth, but allow the soil to dry off completely after flowering. In cooler zones, plant in autumn after the first rains; in Mediterranean zones, plant in late autumn for winter growth.
Sowing
Sow seeds in autumn in seed trays with fine potting mix, barely covering. Germination takes 14–21 days at 15–18°C. Grow on for a season before planting out; flowering may not occur until the second year.
Care
Feed with a balanced liquid fertiliser every 2–3 weeks during active leaf and flower growth. Stop feeding once foliage begins to yellow. Allow leaves to die back fully before lifting corms for storage or leaving in dry ground.
Companion Planting
Plant with ranunculus, freesias, and Dutch irises for a coordinated spring bulb display. Avoid heavy feeders like brassicas that compete for moisture. Do not plant near invasive groundcovers that smother low foliage.
Common Pests & Risks
Aphids cluster on new growth; control with a strong water spray or insecticidal soap. Slugs and snails damage emerging shoots; use iron-based baits or hand pick at night. Fungal disease like botrytis appears in wet weather; improve air circulation and avoid overhead watering.
Harvesting
Cut flowers for bouquets when the buds are just showing colour but before fully open. Harvest in early morning when stems are turgid. Remove spent flowers to prevent seeding, which reduces corm size.
Troubleshooting
Yellow leaves: overwatering or poor drainage during growth; reduce water and check soil. Brown leaf tips: dry air or underwatering; increase moisture but avoid soggy soil. Stunted growth: corms planted too shallow or not soaked; replant at 5 cm depth after pre-soaking. No flowers: corms too small or planted in shade; use larger corms and full sun. Rotting corms: heavy soil or wet winter; improve drainage with sand or grit.
