While not unique to Norway spruce (European larch and Japanese larch have obvious skirts, while mature white spruce has subtle skirts), the skirts are most evident in this evergreen species. With age, the pendulous, dense branchlets in the upper canopy of mature trees hang straight down for several feet and are called skirts. Norway spruce has its dark green needles point forward along the twigs, making this species of spruce easier to grasp with the hand than the more prickly Colorado spruce, whose needles radiate outward from the twigs. It is especially drought tolerant, including young transplants that have been root pruned into ball and burlap form. Like most spruces, it may suffer needle damage due to feeding by the various spider mites and mysteriously shaped "cones" that are rarely seen are actually caused by the chewing of cooley spruce gall aphids on the new growth, resulting in their deformity. Norway spruce is generally a very healthy tree, even under harsh conditions.

It grows in full sun to partial sun in zones 3 to 7. Its only requirement is to not be sited in wet soils, where it will quickly die. It thrives under seasonal drought once it is established and takes well to city pollution. However, it is perhaps the most adaptable common evergreen tree to harsh conditions, including poor, clay, rocky, dry soils of acidic, neutral, or alkaline pH. Norway spruce prefers moist but well-drained, acidic soils that may be organic, sandy, or loamy. As a member of the pine family, it is related to other spruces, as well as the firs, larches, pines, and hemlocks. A distinctive trait of Norway spruce is the strong central leader, horizontal side branches, and vertically pendulous branchlets. It is so common, widespread, vigorous, and healthy that most people do not realize that it is not a native of North America, in spite of its common name. Norway spruce quickly reaches 80 feet in height by 40 feet in spread with its medium to rapid growth rate and adapts to a variety of harsh soil and sparse moisture conditions. It is native to central and northern Europe including Norway, for which it is named, and prefers moist, cool climates. It is found as an ornamental tree in urban environments, a windbreak and snowbreak in both urban and rural areas, and occasionally in pure stands for future harvest in forests. Norway spruce ( Picea abies), an evergreen conifer, is found throughout all of Ohio and much of the United States and Canada as perhaps the most common spruce, rivaled only by Colorado spruce.
