}}Betula grossa, commonly known as Japanese cherry birch, is a species of birch native to Japan, where it grows naturally in mixed woodland on hill and mountain slopes in Honshu, Shikoku , and Kyushu. It was introduced to the West in 1896, but remains rare in cultivation.[1] DescriptionBetula grossa is conical in outline, but its most distinctive feature is its cherry-like bark, with horizontal stripes of reddish-grey becoming dark grey with age, exfoliating in thin papery curls. The dark green leaves are up to 10 cm long and turn golden-yellow in autumn. The shoots are aromatic, and carry long, yellow-brown, male catkins in early spring.

The species is considered closely related to the American birch Betula lenta.[1] Hardiness: RHS H4.[https://www.rhs.org.uk/plants/pdfs/2012_rhs-hardiness-rating] References1. ^1 White, J. & More, D.
