Comprehensive DescriptionRead full entry
CommentsRue Anemone is one of many showy wildflowers that develop in deciduous woodlands during the spring. Both the flowers and foliage are quite attractive. Because the flowers move around easily in the wind, it is sometimes called 'Windflower.' Another scientific name of this species is Anemonella thalictroides. Rue Anemone resembles Enemion biternatum (False Rue Anemone), but its flowers have more petaloid sepals (typically 6-9), while the flowers of False Rue Anemone have only 5 petaloid sepals. Furthermore, its leaves and flowers are arranged in whorls to a greater extent than those of False Rue Anemone. Other Thalictrum spp. in Illinois are much larger plants with wind-pollinated flowers. While the leaflets of these species are similar to those of Rue Anemone, their flowers are quite distinct.
