What is Betula grossa
Betula grossa ,mizume or Japanese Cherry Birch(scientific name: Betula grossa ) is a deciduous tree native to Japan in the birch family, Betulaceae. It grows naturally in moist thickets in mountainous and hilly areas from Iwate Prefecture in Honshu to Shikoku and Kyushu. The tree is 20-25 m tall, with an upright trunk and conical shape with thick branches and leaves. The bark has grayish-red to dark-gray horizontal stripes that curl and peel like thin paper, similar to the bark of the cherry tree. The new shoots are fragrant.
Male flowers in long yellowish-brown caudate inflorescences bloom in early spring.
The wood is heavy and tough, so it is used for building and equipment materials. When a branch is broken, it smells of methyl salutylate. Methyl salutylate is the main ingredient of muscle anti-inflammatory material. The genus name "Betula" is from the Latin word "betu (birch)," and the species name "grossa" is from the Latin word "big. In the Manyo period (710-794), it was used for azusa bows, hence the Manyo name azusa.
