Japanese Larch Overview

Larix kaempferi is sometimes known as Larix leptolepis and commonly as Japanese Larch or Karamatsu. It originates from Central Japan. It is a large, vigorous, deciduous conifer from the Pinaceae family. Forming reddish shoots with light green leaves arranged in bunched whorls. The bright green leaves turn orange and yellow, displaying attractive autumn colouration. The bark is greyish-brown in colour. Cones are oval in shape, coloured green and ripening to brown with age, they measure around 3cm in length, with outward curving scales. Grow in full sun, in moist, well-draining soil.

Common problems with Japanese Larch

Larch tortrix moth caterpillars feed on the cone scales while many types of moth caterpillars (larch pug, case-bearermoth) feed on the foliage.
