The smaller anemones make great plants for semi-shaded aspects in moist soil and as such make good bed fellows with such choice things as Trilliums and Erythroniums.
Certainly plant the European wood anemones of the nemorosa persuasion and don’t miss this little Japanese beauty. It flowers first every year for me so extends the season and its simple single white flowers are set of well by its heavily cut and marbled leaves. Come the first warm days and it quietly disappears till next year. Over a few years it will gently make a mat up to 1metre across from its knobbly brittle rhizomes.
