Many cultivars have been selected for garden use eg Anemone nemorosa 'Allenii' which has large blue flowers. Yellow wood anemone, Anemone ranunculoides, also known as the buttercup anemone, is a similar plant with slightly smaller flowers of rich yellow colouring.
All parts of the plant contain protoanemonin, which can cause severe skin and gastrointestinal irritation. The plant has poisonous chemicals that are toxic to animals including humans, but it has also been used as a medicine. The flowers lack both fragrance and nectar and it has been suggested by some authors that they are primarily self-pollinated, but it has also been demonstrated that they are pollinated by bees and other insects that visit the flowers to collect pollen (Shirreffs 1985). In the wild the flowers are usually white, but may be pinkish, lilac or blue, and often have a darker tint to the back of the 'petals'. The flower is 2 cm diameter, with six or seven petal-like segments (actually tepals) with many stamens. The rhizomes spread just below the soil surface, forming long spreading clumps that grow quickly, contributing to its rapid spread in woodland conditions, where they often carpet large areas. The plants die back down to the root-like rhizomes by mid summer (summer dormant).
The plants grow from underground stems called rhizomes. Plants start blooming soon after the foliage emerges from the ground, with the leaves parted into three segments and the flowers produced in the middle of the foliage on short stems above the foliage with one flower per stem. They are perennial herbaceous plants, growing in early spring from 5 to 15 cm tall. Common names include wood anemone, windflower, European thimbleweed and smell fox. A taxonomic species within the family Ranunculaceae a wood anemone. Anemone nemorosa is an early- spring flowering plant in the Genus Anemone in the family Ranunculaceae.
