The Gold birch (Betula ermanii) belongs to Betulaceae (the Birch family). It is a tall deciduous tree that is native to northward from Chubu district of Honshu to Hokkaido in Japan, as well as the Korean Peninsula, the Sakhalin and the Kamchatska Peninsula. This tree grows in alpine or boreal slopes and can reach 10-15 m in height. The branches are creeping near the ground at upper timberline or heavy-snow region. This tree resembles to white birch, though it grows at higher places. The barks are reddish-tinged grayish-brown. The flowers come in May and June as soon as foliation. The drooping male inflorescences are borne at the tips of branches, and the upright female inflorescences are borne on the short branchlets. The flowering time depends on melting of snow.
