Larches are conifers in the genus Larix, in the family Pinaceae. They are native to much of the cooler temperate northern hemisphere, on lowlands in the far north, and high on mountains further south. Larches are among the dominant plants in the immense boreal forests of Russia and Canada.

European Larch foliage and cones



They are deciduous trees, growing from 15-50 m tall. 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. The leaves are needle-like, 2-5 cm long, slender (under 1 mm wide). They are borne singly, spirally arranged on the long shoots, and in dense clusters of 20-50 needles on the short shoots. The needles turn yellow and fall in the late autumn, leaving the trees leafless through the winter.

Larch cones are erect, small, 1-9 cm long, green or purple, ripening brown 5-8 months after pollination; in about half the species the bract scales are long and visible, and in the others, short and hidden between the seed scales. Those native to northern regions have small cones (1-3 cm) with short bracts, with more southerly species tending to have longer cones (3-9 cm), often with exserted bracts, with the longest cones and bracts produced by the southernmost species, in the Himalaya.
Uses

Larch is valued in forestry for its wood, which is tough, waterproof and durable, with top quality knot-free timber being in great demand for building yachts and other small boats. Larch has also been used in herbal medicine; see Bach flower remedies for details.
Larch is used as a food plant by the larvae of a number of Lepidoptera species.

Larches are often used in bonsai culture, where their knobby bark, small needles, fresh spring foliage and especially autumn colour are appreciated. European Larch, Japanese Larch and Tamarack Larch are the species most commonly trained as bonsai.


Thanks.
