Wood anemone is an early-flowering plants that carpets woods, copses and shady gardens in spring. Individually, the plants are elfin and demure but en masse, sparkling in the spring sunlight, they are a thrilling sight and the first portent of the season’s exuberance.

The principal member of the group is Anemone nemorosa, a British native that you would miss if you went looking for it on a grey day because the flowers close up when the skies are cloudy. As soon as the sun appears the flowers open wide and face upwards to bask in the light and warmth. The plant spreads by a system of thin, twig-like rhizomes that push through the leaf-litter on the woodland floor.
In most parts of the country the flowers are white but in central England many blue forms occur, and in Ireland blue forms often predominate. Nobody consciously breeds Anemone nemorosa, but the diversity of plants in the wild has provided rich pickings for eagle-eyed plant enthusiasts, and dozens of selections have been named.
The earliest of the anemones to flower is Anemone blanda. It is naturally variable but the flowers tend to be deep blue and, at up to 5cm across, much larger than those of Anemone nemorosa, with narrow sepals.

How to grow Anemone nemorosa and wood anemone
Where to grow wood anemones
Although in the wild Anemone nemorosa grows in even the densest woodland shade, it flowers more profusely in clearings where light reaches the woodland floor or in places where the trees have been recently coppiced. Similarly in the garden, anemones will flower in the shade cast by buildings or fences but flower most abundantly when growing around deciduous shrubs or among later-flowering perennials.
Woodland anemones look impressive in the garden when they carry the baton on from snowdrops, and can be planted to cover the soil under trees that later in the year would be too shaded for most plants. They are also perfect companions to magnolias and amelanchier, providing pools of flowers for the shrubs to float above.
As important as shade is moisture and humus. None of the woodland anemones thrive in either dry soils or very rich soils, which tend to produce plants with lots of foliage and not many flowers. The ideal open and friable soil can be achieved by adding lots of leaf mould or composted bark to the soil when you plant your anemones. Thereafter, when the plants are dormant, mulch the area every few years with a thick layer of leaf mould.
Anemone blanda will tolerate both chalky soils and a dry summer.
How to plant wood anemones
Nurseries sell Anemone nemorosa either as growing plants in small pots or as bare corms, which look like pieces of thin twig. I find that the plants that are pot grown establish more quickly and more reliably than the bare corms. Anemone blanda corms are much tougher and can be reliably bought as dried corms. Remember that anemones go dormant soon after they have finished flowering, so to avoid putting a fork or trowel through them when weeding it is a good idea to mark where they are.
Caring for wood anemones
After a few years the plants make a mat of thin rhizomes, which should be divided every few years if you want to create a carpet of the plants. Regular division will also ensure that your plants flower well and that you will have a few to pass on to friends. Simply dig the plant up when it is dormant, carefully tease the rhizomes apart and then replant the pieces.
Growing wood anemones in pots
The conventional wisdom – and one that I have followed – says that woodland anemones will not thrive in pots but Brian Ellis, nurseryman at Avondale Nursery in Warwickshire where the National Collection of Anemone nemorosa is held, assures me that this is not true. He grows the entire collection in large (10L) pots using ordinary multipurpose compost. Each year he strips away the soil at the top and at the bottom of the pot and replaces it with fresh compost that has a slow-release fertiliser added. Keep the pots well watered and in the shade, especially during the summer.
Wood anemone problems
In some years the plants are affected by powdery mildew or leaf spot. This can blemish the foliage but neither are fatal so not worth getting agitated about.
- WOOD ANEMONES IN BRIEF

- Season Spring flowering plants that are dormant during the summer and autumn. Most flower March through to June.
- Hardiness Tough plants that are hardy throughout all of the UK.
- Size Most reach a height of between 12cm and 20cm, and can often form clumps that are several metres wide.
- Conditions Moist but well-drained, humus-rich soil; part shade. Some species will tolerate drier conditions during the dormant period.
