Wikipedia Abstract

Larix kaempferi, known as Japanese larch or karamatsu (唐松) in Japanese) is a species of larch native to Japan, in the mountains of Chūbu and Kantō regions in central Honshū. It is a medium-sized to large deciduous coniferous tree reaching 20–40 m tall, with a trunk up to 1 m diameter. The crown is broad conic; both the main branches and the side branches are level, the side branches only rarely drooping. The shoots are dimorphic, with growth divided into long shoots (typically 10–50 cm long) and bearing several buds, and short shoots only 1–2 mm long with only a single bud. The leaves are needle-like, light glaucous green, 2–5 cm long; they turn bright yellow to orange before they fall in the autumn, leaving the pinkish-brown shoots bare until the next spring.
