Larch
| Scientific Name: | Larix decidua |
| Other names: | European Larch |
Larch is an attractive decorative timber with a prominent grain. Knots are small, numerous and tight. Used for exterior applications, framing and flooring.
Distribution
Although Larch is indigenous to central Europe, it has been extensively planted in New Zealand and the United Kingdom for timber production.
Texture
Larch typically exhibits a relatively fine to medium texture, and the grain is generally straight but can sometimes be spiral or wavy.
Appearance
The heartwood of Larch ranges from a yellow to medium reddish-brown colour, while the sapwood is noticeably paler. Over time, the heartwood can darken, creating more contrast with the sapwood. Growth rings are prominent, defined by denser and darker latewood, knots are usually small, tight and numerous.
Properties
Larch is a moderately dense softwood that provides excellent strength and hardness for a softwood species. Larch has a high proportion of heartwood and also a good degree of natural resistance to decay, when used above ground. The heartwood is difficult to impregnate with preservatives. Relatively easy to work and glue, but can have a corrosive action on steel nails.
