soft windflower; Anemone flaccida
A perennial woodland plant native to East Asia, bearing small white flowers in early spring. The Japanese name means 'two-flower plant' because it often produces two flower stalks from a single stem.
In spring, soft windflowers grow in clusters on the mountain slopes.
The soft windflower is a perennial that prefers damp forest floors.
From 二輪 (にりん, 'two flowers') + 草 (そう, 'grass, plant'), referring to the plant's characteristic of often bearing two flowers per stem.
