Anemone nemorosa is naturally found in Europe growing in deciduous open woodlands in valley floors and the adjoining hillsides forming a carpet effect in the understory, from sea level to an altitude of 2600 m (7,800 ft). 

It prefers an open sunny to semi-shaded protected position and grows in well-drained organic rich moist soils with a pH 5.5-7.0 and is frost and drought tolerant. 

The Wood Anemone is grown for its flowers and spreading habit. It is planted in small or alpine gardens as a ground cover or used in the understory in woodland settings, commonly a long watercourses or around bogs. It is suitable for coastal and low-mountain regions establishing in one season and is moderately long-lived. This perennial is also grown in patio pots of planter boxes and several cultivars are available with varying flower colour. ID 3670
