What is Glaucidium palmatum
Glaucidium palmatum, ( scientific name: Glaucidium palmatum) is a perennial herb of the family Ranunculaceae, one genus and one species endemic to Japan. It grows naturally along streams and on the forest floor in the lower (sub)alpine zone from Hokkaido to the central part of Honshu and in the heavily snowy areas on the Sea of Japan side. It survives in the heavy snowfall areas on the Sea of Japan side by using snow as a blanket. It is also known as "Shirane-aoi". The plant is 30 to 40 cm tall. The leaves are palmate with a diameter of 20-25 cm.
From early summer to summer, two leaves are attached to the top of the flower stalk, and four sepals, which look like petals and are about 7 cm long, are attached to the top of the leaves. There are no petals. The sepals are light pink to light purple in color with a clump of yellow stamens in the center. The flowers are followed by flattened fruits that burst and release seeds in the fall. Although it is called "mallow," it is not a member of the mallow family. The name of the flower is derived from its four sepals, which resemble those of the hollyhock (scientific name: Althaea rosea), which is abundant on Nikko Shiranesan Mountain.
