Anemonastrum flaccidum, commonly known as the flaccid anemone or soft windflower, is a species of flowering plant in the family Ranunculaceae. It is a low-growing perennial native to East Asia.
Anemonastrum flaccidum grows to about 0.1 m (4 in) tall. It flowers from March to June, depending on the region. The flowers are approximately 2 cm in diameter and have white sepals that resemble petals.
Many stems bear two flower stalks, a characteristic that gives rise to the plantâÂÂs Japanese name, äºÂ輪è (nirinso, meaning "two-flowered plant"). The plant spreads by rhizomes and often forms dense colonies.
Anemonastrum flaccidum is native to the Amur River region, Sakhalin, central, eastern, and southern China, Korea, and Japan.
The species typically grows in moist, shaded environments such as forest floors, often near streams and ravines, in loose, peaty soils.
