The Siberian Larch is a deciduous tree with broad pyramidal-shape. It has arching branches with long soft green needles turning bright yellow in the fall. Tolerant of most soil conditions. Little pruning is needed. Prune broken or damaged limbs.This tree has not done well in my zone 3a garden and I believe it is due to it's location.

This larch species is native to western and central Siberia. It has a horizontal, spreading habit and densely clustered needles on the spurs that are about 1 to 1.5 inches long. Its cones are about 1 1/4 to 2 inches long and are borne upright on the twigs. It has dark brown to gray-brown scaly bark. It is rarely planted in landscapes, but is used a lot for lumber. Its softwood is rot resistant with lots of resin and tannins within and is hard for a coniferous tree. The city of Venice, Italy is supported by great posts of this wood into the swampy ground. It can live over 700 years. There are some mature trees that were planted at Morton Arboretum in northeast Illinois. Some site in North Dakota has some doing well.
