Picea Rubens commonly known as Spruce is an evergreen conifers tree of the genus Picea and in the family Pinaceae. The plant is 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.  Few of the popular common names of the plant are yellow spruce, West Virginia spruce, eastern spruce, he-balsam, red spruce and blue spruce. Genus name is reportedly derived from the Latin word pix meaning pitch in reference to the sticky resin typically found in spruce bark. Specific epithet both are in reference to the fact that mature needles of this tree become glaucous (acquire a waxy white bloom) with age. Spruce is long-lived, often achieving ages greater than 350 years.

Plant Description

Spruce is a perennial, shade-tolerant, late successional, coniferous tree that grows about 18–40 meters (59–131 ft.) tall with a trunk diameter of about 60 centimeters (24 in), though exceptional specimens can reach 46 m (151 ft.) tall and 30 cm (12 in) diameter. The plant is found growing in moist but well-drained sandy loam, often at high altitudes. The tree is upright and straight, with a narrow crown. Root system has a minimum depth of 13 inches (33 centimeters). Twigs are orangish brown, finely hairy (may need a hand lens); as with all spruces, needleless twigs covered by short sterigmata (short pegs).  Buds are orange-brown, small with loose scales, with a densely pubescent to glabrous texture.

Barks are grayish brown on surface, more reddish brown beneath with irregular, fine flaky patches, thin, and scaly. Woods are light, soft, have narrow rings, and have a slight red tinge. Leaves are needle-like, yellow-green, 12–15 millimeters (0.47–0.59 in) long, four-sided, curved, with a sharp point, and extend from all sides of the twig. Needles are pungently aromatic when crushed. Foliar buds are reddish brown in color, measuring 0.2 to 0.32 inch (5 – 8 mm), with an acute apex. Species is monoecious; males are cylindrical reddish but turning yellow-brown; females are purplish green. Flowers are followed by chestnut brown ovoid cone, 1 to 1 1/2 inches long, cone scale margins entire. Seed is dispersed in the fall and cones tend to drop their first winter.
