Larix kaempferi - Japanese Larch
Larix kaempferi commonly known as Japanese Larch is native to Japan. This species of larch is easily distinguished from the European Larch by its blue-green foliage in summer and the reddish appearance of its bare branches in winter.
It is a medium-sized to large deciduous coniferous tree. It is grows 20–40 m (66 – 132 ft) in height, with a trunk up to 1 m (3.3 ft) diameter. The crown is broad conic; both the main branches and the side branches are level, the side branches only rarely drooping.
The young terminal growth shoots are pendulous and long, russet colored, and by their second year are red with waxy bloom, shallowly furrowed, and roughened by needle bases of the previous year. The winter buds at their tips are reddish-brown and resinous; the buds at the sides are smaller. The pointed needles, 2.5-3.5 cm (1-1.5 in) long are scattered around the young shoots (‘juvenile’ foliage), but on the older twigs are in rosette of twenty to thirty, all springing from a short spur shoot. They are soft and blue-green, slightly wider than those of European Larch, with two stomatal bands beneath, and they fade to a rich orange color before they fall in autumn.
The flowers of both sexes are found on the same tree, and they are smaller than those of European Larch. They appear a little in advance of the needles. The small round brown males are set on the underside of the branches, and are pale yellow when ripe. The female conelets are erect and cream or greenish, with reflexed bracts. They later harden, and become brown squat and broad cones, with scales which are reflexed at their edges. The cones stand are erect, are rounded in outline, and are 2.5-3.5 cm (1-1.5 in) long. They ripen by October, and their scales open though the cones persist on the tree for an indefinite time.
The bark of young trees is at first smooth and reddish, becoming thick, brown and scaly or finely fissured with age. The branches are irregular, mostly horizontal and often the leader has a corkscrew formation is reddish-brown. It is coarse in texture and resinous but strong, hard and naturally durable, providing a multi-purpose timber, particularly used for fencing, gates, and estate repair work.
Foresters appreciate this tree as a fast starter, though not, overall, a producer of very high volume. It is practically free of canker, and is useful for suppressing ground vegetation, though it will not withstand shade itself.

Hybrid Larch, L. X eurolepis Henry, is a natural cross between European Larch and natural cross between European Larch and Japanese Larch first raised in 1897 (accidentally) and in 1904 (deliberately) at Dunkeld in Perthshire. It first arose through the chance cross-pollination of female flowers of Japanese Larch by male flowers of the European kind. It shows remarkable ‘hybrid vigour’, growing faster than either of its parents, and has been planted on a considerable scale, but seed is still scarce. Its botanical characteristics are variable, but intermediate between those of the two parents.

Larix decidua - European Larch
Larix decidua commonly known as European Larch is native to Europe. It is best known deciduous conifer in Europe. The European appreciate it as a tree graceful in form, and of airy light foliage which reflects so well the passing of changing seasons.
L. decidua is a medium-size to large growing tree that grows 25–45 m (82 – 148 ft) in height, with a trunk up to 1 m (3.3 ft) diameter, specifically it grows up to 55 m (180 ft) tall with 2 m (6.6 ft) diameter trunk. The crown of the tree is looks like a conic when young and becoming broad with age; the main branches are level to upswept, with the side branches often pendulous.
The young terminal shoots are pendulous and long, straw colored, shallowly furrowed, and roughened in their second season by needle bases of the previous year. The brown winter buds at their tips have many scales, and are non-resinous; the buds at the sides are smaller. The short spur shoots become very dark brown, with buds that are short and rounded. The pointed needles,  3 – 3.5 cm (1.2 – 1.5 in) long, are scattered around the young shoots (‘juvenile’ foliage), but on the older twigs are in rosettes of twenty to thirty, all springing from a short spur shoot. They are soft and bright emerald green at first, becoming duller later, and fade to a pale straw color before they fall in autumn.
Both sexes of flowers are found on the same tree. The flowers appear a little in advance of the needles. The small round males (found on the underside of the twigs) are clusters of golden anthers when ripe. The females are erect and usually rosy-pink – a soft conelet, which later hardens and turns cylindrical, with brown closed scales. The cones stand erect, have tapering outline and are 2.5-3.5 cm (1 – 1.5 in) long. They ripen by October, and their scales open, though they persist on the tree for an indefinite time.
At first the bark is thin and greyish-brown, becoming thick, brown (sometimes with a purplish sheen) and fissured longitudinally with age, when it is sometimes shed in small plates. The inner layers show a carmine-red tint. Some stems are disfigured by canker. The branches are irregular, mostly downswept from the trunk, and then upturning. The fairly narrow sapwood is yellowish, and the heartwood is reddish-brown. It is coarse in texture and resinous, but strong, hard and naturally durable, providing a multi-purpose timber, particularly used for fencing, gates, and estate repair work, also for the planking of fishing boats.
Though a well-established tree, European Larch is not widely planted now because Japanese and Hybrid Larch grow faster and are canker-free; only certain strains of European Larch avoid this trouble. Yet the trees is of rapid early growth, sometimes exceeding 60 feet in 20 years.
Hybrid Larch, L. eurolepis Henry, an important natural cross, is referred to under Japanese Larch.
