Larch is a deciduous coniferous tree, native to cool climates in the Northern Hemisphere. It has a pyramidal growth habit and sheds its needle-like leaves in the fall. Of the 10 to 12 species of larch widely distributed throughout the northern areas of the United States, at least four of them are found in Ohio. - Commonly known as American Larch or Tamarack, Eastern larch is found in the northeastern and northwestern counties of Ohio. It is the only deciduous conifer native to Ohio. Growing to a height of 30 to 70 feet, Eastern larch has a reddish brown bark. Its pale bluish-green leaves form in clusters and are 3/4 to 1 inch long. It bears small oval-shaped cones that are 1/2 to 3/4 inch long. The cones remain on the tree throughout the winter.
- European larch is better adapted to Ohio's climate than the native Eastern larch, according to Ohio State University. It is a deciduous, evergreen conifer that grows to a height of 50 to 75 feet. European larch has leaves that are approximately 1 inch long and light bluish-green in color. It has a scaly gray bark that becomes furrowed with reddish brownish inner bark as the tree matures. European larch bears 1 to 1 1/2 inch long ovoid cones in the fall and early winter.
- Japanese larch is hardy throughout Ohio. It grows to a height of 50 to 60 feet, and has a symmetrical and graceful pyramidal form. Its leaves are a little over an inch in length and are grayish to bluish-green in color. Japanese larch bears egg-shaped cones that are approximately 1 inch long.
