Pinus resinosa, known as red pine or Norway pine, is a pine native to North America. It occurs from Newfoundland west to Manitoba, and south to Pennsylvania, with several smaller, disjunct populations occurring in the Appalachian Mountains in Virginia and West Virginia, as well as a few small pockets in extreme northern New Jersey and northern Illinois.
The red pine is the state tree of Minnesota. In Minnesota the use of the name "Norway" may stem from early Scandinavian immigrants who likened the American red pines to the closely related European red pines back home.
Red pine is a coniferous evergreen tree characterized by tall, straight growth in a variety of habitats.[7] It usually ranges from 20β35 m (66β115 ft) in height and 1 m (3 ft 3 in) in trunk diameter, exceptionally reaching 43.77 m (143 ft 7 in) tall.[8] The crown is conical, becoming a narrow rounded dome with age. The bark is thick and gray-brown at the base of the tree, but thin, flaky and bright orange-red in the upper crown; the tree's name derives from this distinctive character. Some red color may be seen in the fissures of the bark. The species is self pruning; there tend not to be dead branches on the trees, and older trees may have very long lengths of branchless trunk below the canopy.
The leaves are needle-like, dark yellow-green, in fascicles of two,[7] 12β18 cm (4 3β4β7 in) long, and brittle. The leaves snap cleanly when bent; this character, stated as diagnostic for red pine in some texts, is however shared by several other pine species. The cones are symmetrical ovoid, 4β6 cm (1 1β2β2 1β4 in) long by 2.5 cm (1 in) broad, and purple before maturity, ripening to nut-blue and opening to 4β5 cm (1 1β2β2 in) broad, the scales without a prickle and almost stalkless.
