Pinus resinosa, known as red pine, is a pine native to North America. It is a coniferous evergreen tree characterized by tall, straight growth in a variety of habitats. It usually ranges from 20?35 m (66?115 ft) in height and 1 m (3 ft 3 in) in trunk diameter.
The leaves are needle-like, dark yellow-green, in fascicles of two 12?18 cm (4 3?4?7 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, 4?6 cm (1 1?2?2 1?4 in) long by 2.5 cm (1 in) broad, and purple before maturity, ripening to nut-blue and opening to 4?5 cm (1 1?2?2 in) broad, the scales without a prickle and almost stalkless.
