Where to plant
Also known as winter aconites, Eranthis will grow in both sun and shade, in a moist
but well drained soil. They look best when grown in large numbers for a naturalised effect.
How to plant in the ground
1. Before planting, we recommend you soak the bulbs in warm water overnight to soften them,
ready for establishment.
2. Prepare the soil with a high-quality compost and plant approximately 5cm deep in groups
and 5cm apart for the best effect.
3. If soil is poor and sandy, organic matter such as a nutrient rich manure will help growing
4. Water well, allowing for the soil to settle around the bulbs and keep moist over the growing
5. Adding a layer of mulch can help to keep the soil moist in warm spring weather.
How to plant in containers
1. Eranthis has shallow roots and tubers which grow just below the surface of the soil, so they
can be grown in pots, containers, and window boxes.
2. A container with drainage holes is ideal to keep the soil most. Fill three quarters of the
container with potted compost with added grit.
3. Plant your tubers 5cm deep and then cover with soil until the pot is filled to 1cm from the
4. Keep soil moist over autumn and winter.
5. If you wish to force indoors, move to a cold, dark place to trick the bulbs into thinking its
6. Move to a location that gets full sun in February and early March when growth appears.
1. Ensure the plants are kept moist during the growing season, and over summer.
2. Feed with a high potash fertiliser.
3. Always keep the soil weed free to allow the plants to spread and avoid overcrowding.
4. Allow the foliage to die back naturally to feed the bulbs for the following growing season.
5. If grown in grass, avoid mowing until foliage has yellowed and died back.
6. Tubers can be dug up shortly after flowering has finished and transplanted to another spot
in the garden.
Pests and Diseases
Eranthis is virtually pest and disease free, but may be susceptible to smut fungus, if small spots are
noticed on the plant, remove the infected part, and dispose to avoid spread.
