    Interesting, this tree while considered a conifer, loses its leaves and is a dominant tree species in large parts of Siberia, Northeast Europe and Canada. The Russian or Siberian Larch reaches 65 to 160 feet in height with a 3 foot trunk diameter.

    The RUSSIAN LARCH/LARIX DECIDUA LARIX SIBIRICA/SYBERIAN LARCH is the softwood species with properties of real hardwood. The summer wood of annual rings is wide as spring wood and it is what makes Larch strong and durable like Oak.
    The remarkable properties of Larch wood has been known in Europe for centuries. The entire Italian city of Venice is propped by thousands of durable, naturally rot resilient piles.
    It is a medium-size to large deciduous coniferous tree reaching 20-40 m tall, with a trunk up to 1 m diameter. The crown is conic when young, becoming broad with age; the main branches are level to upswept, with the side branches often pendulous. 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. It is most easily distinguished from the closely related European Larch by the shoots being downy (hairless in European Larch). The leaves are needle-like, light green, 2-4 cm long, and turn bright yellow before they fall in the autumn, leaving the pale yellow-buff shoots bare until the next spring. This tree is said to account for around 20 - 25% of all the trees grown in the world and its timber is mainly used for construction and building projects: covering facades of the houses and public buildings, erection of terraces, fences, floors and boarding, including boats, yachts. Our main timber products are used in decking, cladding, and flooring.
