The Wooly geranium (Geranium erianthum) belongs to Geraniaceae (the Geranium family). It is a perennial herb that is native to northern Honshu, Hokkaido in Japan, as well as from the central part of the Korean Peninsula to northeastern China, in the Russian Far East and North America. This herb grows in sub-alpine to alpine grasslands, and can reach 20-50 cm in height. The leaves are divided into 5-7 lobes palmately, and the segments are further notched. The stems and petioles are covered with dense, descending, appressed hairs. The magenta flowers bloom on the stem apices from June to August. It is called "東北老鸛草" (dong bei lao guan cao) in Chinese.
In Korean, it's called "kal-mi-son-ip-pul" (갈미손잎풀). This is a compound word consisting of "kal-mi" (갈미) + "palmate" (son-ip: 손잎) + "grass" (pul: 풀). "kal-mi" (갈미) is named after "Kalmi Peak" (갈미봉) in North Pyongan Province, where it was discovered.
