What is Coptis quinquefolia
Coptis quinquefolia or baika-oren (scientific name: Coptis quinquefolia) is an evergreen perennial herb of the genus Coptisa of the family Ranunculaceae, endemic to Japan. It grows wild in forest margins in mountainous areas from the southern Tohoku region to Kyushu and Shikoku. The grass is low, 5 to 10 cm tall. The thread-like stems crawl underground to reproduce and produce leaves. It has five leaves, which resemble the leaves of the araliaceae (five-leafed magnolia), hence its other name, gokayo-hawaioren (five-leafed magnolia). In spring, white flowers resembling plum blossoms bloom at the tips of long, slender, brown flower stalks. However, what appears to be a white flower is a calyx, and the real flower is a small yellow pendulous one in the center. After the flower, a boat-shaped fruit is produced. The name "baika-oren" comes from the fact that the calyx, which looks like a flower, resembles a plum blossom.
