Mountain hemlock (*Tsuga mertensiana*) is an evergreen, coniferous tree whose small seed cones are light to dark purple. It prefers partial shade and moist, well-drained soil. Prefers colder climates where the growing season is short and the winter is long.

It is an evergreen coniferous tree growing up to 30 m tall and 1.1 m in trunk diameter under forest conditions. The crown is compact and pyramidal, growing up to 8 m wide. The bark is thick, reddish-brown and becomes fissured between scaly ridges. The leaves are flattened, with a rounded or slightly notched apex.

Tsuga chinensis is a large tree with bark that is a blackish brown in colour. The scaly bark has irregular longitudinal breaks, and lenticels that are very inconspicuous. The outer bark is about 6 mm thick with alternating tiered layers of pale yellowish brown corky bark, and brown lignified fibrous bark. The newly formed periderm is a purplish red. The inner bark is about 4 to 5 mm thick and pale reddish brown in colour. It is fibrous in texture with minute, almost inconspicuous sclereid, or stone cell groups. The cambium as well as the newly formed phloem are nearly inconspicuous. Freshly cut wood is a pale yellowish white with inconspicuous wood rays. The branchlets that have leaf-cushions. The leaves are arranged spirally in a manner more or less 2-ranked. They are linear and flat in shape and olive green in colour. The upper side of the leaf is grooved and keeled, while the underside has 2 white stomatic bands. The apex of the leaves are emerginate and they measure 16 to 20 mm long. The petioles are crooked. The foliage is very similar to that of T. heterophylla, but T. chinensis has nodding shoots and the stomatic bands are paler and more sparse. Also the colour above is a paler yellowish-green. The stamenate flowers appear singly on one-year-old shoots, or in groups of 1 to 5 on two-year-old shoots. They are a dull purple in colour and measure about 8 mm.
