Larix Lyallii

Eastern Larch, American Larch
Graceful Larches are some of the few cone-bearing trees that drop their colorful autumn foliage. Once their clusters of needle-like leaves fall, the rose-shaped cones remain, dotting the branches through winter.
Larch is only indigenous to the hilly regions throughout Central Europe, where it forms large forests in the Alps, but it has for long been largely cultivated throughout Europe. It was first introduced into England in 1639.
Siberian Larch, Russian Larch LAR-iks rus-I-ka
Deciduous conifer, to 100 ft (30 m) tall, crown narrow and conical, branches erect on young trees, but horizontal on old trees.
American Larch
(Larix larcina (Duroi) K.Koch)
LEAVES: Needles not evergreen; occur singly near the ends of the twigs, elsewhere in clusters of 10 or more; about 1" long, pale green, turning yellow and falling from the tree during the autumn.
Watering: Larch can be very sensitive to watering - as I've learned the hard way. Nursery grown trees must not ever be allowed to dry out, or to stand in water.
The golden larch is a lovely deciduous conifer whose lacy foliage turns golden in autumn. Its bright green needles are slightly larger than those of the European larch.

Another tree was reported as tall as 184 feet (56 m) in Baden, Germany. In the Alps, some old trunks have bark one-foot thick. Larches are important timber trees in Europe and planted on a large scale as a timber crop.
On larch:
Needles discoloured becoming purple or black and fall off prematurely
Bud flushes abort, shoots wilt and dieback. The entire crown of trees can dieback
Bleeding cankers can occur on trunks, stems and side shoots ...
Larch branches, so prettily studded with tiny nodules and flower-like cones are highly decorative, especially if you can find some which are smudged jade-green or grey with lichen.

Insects: Larch Sawfly most destructive pest with periodic epidemics defoliating stands over large areas and killing many trees. (Trees die after 6-9 years of heavy defoliation.) Larch Casebearer also cause extensive mortality in some areas.
The larches prefer a moist soil on the acidic side. Under good conditions with ample soil moisture, the fast growing Japanese larch should be 20 ft tall in 15 years, 50 ft tall in 40 years, and 90 ft tall at maturity in 80 years.

The needles of the Lebanon cedar look like those of the Larch, except that they are evergreen. The needles are grouped in tufts of 30-40. They are about 1/2-1 1/2 inches (1.5-3.5 cm) long, stiff, and four-sided, tapering towards their points.
If varieties such as Japanese maples, crab apples, larch and beech do not have cold conditions, they will be unable to go through their natural growing cycles, and will thus soon weaken and die.
