The sapwood and heartwood of larch are very different. The sapwood is narrow and light yellowy-brown in colour, while the heartwood, when freshly cut, is reddish brown and darkens over time. Its texture is relatively fine and its grain is usually straight. Its high resin content makes the heartwood very durable.
It is an easy wood to work, even if the resin tends to gum up saw blades. It nails, screws and glues without any problems. It cleans up well. It is used for heavy joinery work, door and window frames, shingles, posts, planks and also country-style furniture.
