Common Name :European larch,Larch
Larix decidua is a medium-size to large deciduous coniferous tree reaching 25–45 m tall, with a trunk up to 1 m diameter (exceptionally, to 55 m tall and 2 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. The leaves are needle-like, light green, 2–4 cm long which turn bright yellow before they fall in the autumn, leaving the pale yellow-buff shoots bare until the next spring.
The cones are erect, ovoid-conic, 2–6 cm long, with 30-70 erect or slightly incurved (not reflexed) seed scales; they are green variably flushed red when immature, turning brown and opening to release the seeds when mature, 4–6 months after pollination. The old cones commonly remain on the tree for many years, turning dull grey-black.
It is very cold tolerant, able to survive winter temperatures down to at least -50°C, and is among the tree line trees in the Alps, reaching 2400 m altitude, though most abundant from 1000–2000 m. It only grows on well-drained soils, avoiding waterlogged ground.
Tamarack was employed medicinally by a number of native North American Indian tribes who used it to treat a variety of complaints. It is used in the treatment of jaundice, anemia, rheumatism, colds and skin ailments. It is gargled in the treatment of sore throats and applied as a poultice to sores, swellings and burns. A tea made from the leaves is used as an astringent in the treatment of piles, diarrhea etc. An infusion of the buds and bark is used as an expectorant. The needles and inner bark are disinfectant and laxative. A tea is used in the treatment of coughs. A poultice made from the warm, boiled inner bark is applied to wounds to draw out infections, to burns, frostbite and deep cuts. The resin is chewed as a cure for indigestion. It has also been used in the treatment of kidney and lung disorders, and as a dressing for ulcers and burns.

Larix decidua is cultivated as an ornamental tree for planting in gardens and parks.
The wood is tough and durable, but also flexible in thin strips, and is particularly valued for yacht building; wood used for this must be free of knots, and can only be obtained from old trees that were pruned when young to remove side branches.
Small larch poles are widely used for rustic fencing.
