The common hemlock of E North America is T. canadensis, an ornamental tree (sometimes cultivated as a hedge) with small cones and short, dark green leaves so arranged as to give the branchlets a flattened appearance.

One of the two Western hemlocks ( T. heterophylla, the tallest tree of the genus) has more valuable wood, which is used in construction work. The ground hemlock is a species of yew . The poison hemlock and water hemlock are herbs of the family Umbelliferae ( carrot family) of the division Magnoliophyta . True hemlock is classified in the division Pinophyta , class Pinopsida, order Coniferales, family Pinaceae.
