Hemlock trees are characterized by wide, linear needles with short, rounded ends. Unlike many types of evergreen trees, the hemlock's needles grow on small stems attached to twigs and are one of the tree's most distinguishing characteristics. Hemlock tree needles are green, and have two fine white lines on their under surface. The small, papery pine cones produced by the hemlock are about 3/4 inch long.Know More
The bark of hemlock trees, ranging from medium brown to orange, is especially notable for its cork-like and heavily ridged texture. However, in young trees, the bark is much smoother. Hemlock tree bark was traditionally used for its high levels of tannin to treat animal hides.
While Eastern species of adult hemlock trees are conical and spreading in shape, the Western species of the tree has a much more narrow, conical shape, similar to a Douglas fir. Hemlocks are also notable for their thin, delicate branches that have drooping tips at the ends, making them look quite distinctive from other major types of evergreen trees such as spruce and fir trees. This evergreen tree averages a height of 60 to 100 feet tall and can have a trunk up to 4 feet in diameter.Learn more about Trees & Bushes

For trees to reach full growth, it depends on the climate and the water available. In tropical climates with warm weather and a plentiful supply of water, a tree can become fully grown in 30 years. A tree in cooler regions may take several hundred years to reach full maturity.Full Answer >
The Iowa State University Extension explains one way to differentiate between a spruce tree and a pine tree is to look at the needles. Spruce needles grow directly from a branch individually, and pine needles grow in bunches of two, three or five. Also, the bark of a spruce tree is rough rather than smooth, which sets them apart from fir trees.Full Answer >
Pine trees can be identified by examining their needles, bark, cones and growth form and comparing the results to a field guide or dichotomous key. Additionally, considering the geographic location of the trees can reduce the list of possible species. For example, loblolly pines are restricted to the southern United States, while ponderosa pines are only found in the western United States.Full Answer >
