Corm Dormancy/Pre-chilling
4-6 weeksCorms are hard, dry tubers requiring a cold period to break dormancy and trigger flowering.
Chill corms at 40-50°F for 4-6 weeks before planting. Can be done in refrigerator or outdoors in winter.
Sprouting & Root Development
2-4 weeksAfter planting chilled corms, shoots emerge and root systems establish in cool, moist soil.
Keep soil consistently moist but not waterlogged. Provide cool temperatures (40-55°F ideal). Light watering until foliage appears.
Vegetative Growth
3-4 weeksFeathery, finely-divided foliage emerges and rapidly elongates. Plant develops multiple stems with delicate leaves.
Maintain moderate moisture and cool temperatures. Can tolerate light frost. No feeding necessary if soil is amended; avoid excess nitrogen.
Flowering
2-4 weeks per flower; successive blooms over 4-6 weeksLarge, silky single flowers open, typically deep red with dark stamens and pale reverses. Blooms last 2-3 weeks.
Pinch off faded flowers to encourage additional blooming. Provide support in windy locations. Keep soil moderately moist. Remove spent flowers immediately to extend bloom.
Senescence & Dormancy
3-4 weeksFoliage yellows and withers; corms store energy and enter dormancy for summer rest.
Reduce watering gradually as foliage dies back. Once completely dry, lift corms, allow to cure in dry location, and store in cool (50-60°F), dry conditions until next planting season.

Early season nectar source
WildlifeAnemone flowers attract early pollinators including bees, hoverflies, and other beneficial insects searching for nectar in spring when few other flowers are available. [source]
Harvest Tips
Cut flowers in early morning when petals just open fully. Harvest by cutting stems at soil level with a sharp knife. Immediately place in cool water with flower food. Anemones continue opening in the vase and last 7-10 days. For garden enjoyment, deadhead spent flowers to encourage more blooms throughout the season.
Fun Facts
- 🌱 The name 'Anemone' comes from the Greek word for 'wind,' as the flowers are famously delicate and move gracefully with even gentle breezes.
- 🌱 De Caen and Hollandia are both historically important garden cultivars developed by Dutch horticulturists in the 20th century, selected for their superior cut-flower qualities and reliable performance.
- 🌱 Unlike many spring bulbs, anemone corms must be pre-chilled to break dormancy and initiate flowering, mimicking their natural Mediterranean and mountainous alpine habitat winters.
