Picea rubens, commonly known as red spruce, is a species of spruce native to eastern North America, ranging from eastern Quebec to Nova Scotia, and from New England south in the Adirondack Mountains and Appalachians to western North Carolina.
This species is also known as yellow spruce, West Virginia spruce, eastern spruce, and he-balsam.
Red spruce is a perennial, shade-tolerant, late successionalconiferous tree which under optimal conditions grows to 18–40 m (59–131 ft) tall with a trunk diameter of about 60 cm (24 in), though exceptional specimens can reach 46 m (151 ft) tall and 100 cm (39 inches) in diameter. It has a narrow conical crown. The leaves are needle-like, yellow-green, 12–15 mm (15⁄32–19⁄32 in) long, four-sided, curved, with a sharp point, and extend from all sides of the twig. The bark is gray-brown on the surface and red-brown on the inside, thin, and scaly. The wood is light, soft, has narrow rings, and has a slight red tinge. The cones are cylindrical, 3–5 cm (1 1⁄4–2 in) long, with a glossy red-brown color and stiff scales. The cones hang down from branches.
Red spruce grows at a slow to moderate rate, lives for 250 to 450+ years, and is very shade-tolerant when young. It is often found in pure stands or forests mixed with eastern white pine, balsam fir, or black spruce. Along with Fraser fir, red spruce is one of two primary tree types in the southern Appalachian spruce-fir forest, a distinct ecosystem found only in the highest elevations of the Southern Appalachian Mountains. Its habitat is moist but well-drained sandy loam, often at high altitudes. Red spruce can be easily damaged by windthrow and acid rain.
