What are anemones?
Anemone is a genus of plants which includes wood anemones, spring bulb anemones and Japanese anemones and can be both early-flowering bulbs and autumn blooms. Wood anemones are a group of shade-loving herbaceous perennials composed of several genera, although Anemone nemorosa is possibly the best known. They originate in woodlands and hedgerows in Europe and North America. Japanese anemones will be regulars in many people’s gardens, bringing colour perennially in late summer and autumn. These enjoy well-drained soil and slight shade. Spring bulb anemones grow from rhizomes or tubers and emerge in spring.
When do anemones flower?
Wood anemones are spring flowering plants that are dormant during the summer and autumn. Most flower March through to June. Japanese anemones flower between June and October. Spring bulb anemones should be expected along with your bulb display in the spring months.
How to grow and how to plant anemones
Wood anemones like moist but well-drained, humus-rich soil and part shade. Some anemone species will tolerate drier conditions during the dormant period. They are tough plants that are hardy throughout all of the UK. Most reach a height of between 12cm and 20cm, and can often form clumps that are several metres wide. The majority of anemones dislike very wet winters and waterlogged soil. Japanese anemones can be planted between May and September for flowering in September October.

Anemones chosen by plantswoman Marina Christopher
This tuberous anemone produces an attractive rosette of dissected green foliage in early spring. Flowering stems unfurl from the centre to reveal large vibrant blooms in shades of white, pink, red or purple with an occasional pale lemon. A central white – or occasionally, as here, pink – halo around a cluster of stamens completes the picture of this flamboyant flower, which has the appropriate colloquial name of peacock windflower. Stamens vary in colour through black, green and blue. If happy, will naturalise to form large colonies. Height 20cm. Origin Greece, Turkey. How to grow this anemone Well-drained soil in sun or dappled shade. Hardiness RHS H5, USDA 8b-10b. When this anemone flowers Early spring.
Anemonella thalictroides f. rosea ‘Oscar Schoaf’
I generally avoid double flowers as many are sterile and so don’t provide sustenance for insect pollinators, but I make an exception for this exquisite rue anemone. A diminutive woodlander with perfectly double, rosy-pink flowers and thalictrum-like foliage, hence its name. This anemone flowers in late April and remains in flower for many weeks. It is best grown among plants of similar stature else it can be easily lost among the larger foliage of plants such as hostas. A little woodland gem. Height 10cm. Origin Eastern North America. How to grow this anemone Humus-rich, well-drained soil; dappled shade. Hardiness USDA 5a-8b. When this anemone flowers Mid to late spring, summer dormant.
An anemone from Milwood Plants
Anemone nemorosa ‘Vestal’
A beautiful and robust anemone cultivar with flowers that have a central white cushion made up of stamens that have become petaloid, sitting on a corona of white petals. 15cm. AGM. RHS H5, USDA 5a-8b.
An anemone from Avon Bulbs
One of the nicest of the perennial anemones. It makes drifts of dainty, blue anemone flowers atop fine foliage. Prefers rich soils and semi-shade. 20cm. AGM. RHS H6, USDA 5a-8b.
