Growing Spring Anemones from Corms Everything You Need to Know

When to Start?

Autumn Planting: Ideal for areas with mild winters. If you live in a mild winter region, pre-sprout and plant directly in the garden (Spain, France, Italy). For colder regions, (The Netherlands, Germany, Belguim North of France) start by planting in pots and trays, then move them under cover. Protect the plants with horticultural fleece if temperatures drop below -6°C. If you own a greenhouse or polytunnel, you can plant them.

Late Winter Planting: Best for cold, wet climates (NL, DE, etc). Begin in January or February using seed trays or P9 pots in a frost-free environment. Once germinated, move the plants to a light location, such as a greenhouse, under a cold frame, or in a transparent box. By mid-March, transfer outdoors for May or June blooming.

For first-time growers, it's highly recommended to plant half in autumn and the rest later, if weather permits. If you are new to gardening, go for the January/February planting.

Planting Tips:

Spacing: Keep corms 20 cm apart. In flower beds, fit four plants in a 75 cm width. Avoid overcrowding pots, using one plant per 5 to 7 liters of compost.

Preparation: Soak dry corms in water for six hours to help them expand. Caution: soaking for longer risks deterioration.

Soil: Use potting soil mixed with perlite for better drainage. Plant with the corm's "pointy size" facing down. Not sure? Plant them on their side.

Storage: After planting in pots or trays, store them in a 10°C to 15°C room. Once sprouts appear, typically in two weeks, shift them to a brighter location, preferably in a greenhouse or under a cold frame.

Transplanting: When they outgrow their initial pot or tray, move them to larger containers or the garden, ensuring good soil drainage. Add perlite to heavier compost.

Protection & Care:

Cold Weather: If temperatures drop below -8°C, protect your plants with fleece. Anemone leaves are sturdy but the better you treat them, the better they will grow.

Flower Damage: Flowers aren't frost-resistant. If frozen, trim them, and the plant will focus on new growth.

Harvesting Flowers and Bulbs:

Wait until the blooms have opened once. They will further open in vases and can stay fresh for up to 10 days with regular water changes. Save the corms or bulbs for next season by pulling the wilted plants. If you garden on sandy soil, you can leave them in the ground, and they will return in autumn.
