Japanese larch (Larix kaempferi) — identification, habitat & look-alikes

Japanese larch is one of the unusual that turns gold and drops its needles in fall. It is native to central Japan and planted as a large landscape tree in cooler U.S. regions.

Appearance

Appearance: This broad, conical tree usually reaches about 70–90 ft (21–27 m) in cultivation. Soft green needles grow in brushlike clusters and turn yellow to orange before falling.
Leaves: The needles are about 1–2.5 in (2.5–6.4 cm) long, soft to the touch, and marked with pale bands underneath.
Fruit: The upright cones begin green to purplish and mature golden brown. Their scale tips bend outward, a useful clue for separating this tree from European larch (Larix decidua).

Look-alikes

European larchLarix decidua

Check a mature cone: Japanese larch has scale tips that bend outward, while European larch lacks those strongly bent tips.

Why they get mixed upBoth are deciduous larches with soft needles in clusters.

Where it lives

Typical habitats: large gardens
lawns
woodlands
Range: It is not native to the United States. It has been introduced in New York and is planted elsewhere in northern and cool-temperate areas.
Preferred conditions: It grows best in full sun and moist, well-drained, acidic soil where summers are cool and winters are cold.

Growing it

Care: It is suited to 4a–7b. Hot, humid summers, dry soil, deep shade, and urban pollution can cause poor growth.
Propagation: It can be propagated from seed.

Conservation

IUCN Red List: LCLeast ConcernLow risk of extinction
