|Picea mariana is a small to medium sized evergreen conifer reaching 30 to 70 feet tall, with a limited spread. The habit is distinctly spire-like. The smaller size makes it more usable in residential landscaping, but care must be taken in placing the prickly formal spruces.
The leaves are 4-sided, dull bluish-green, to 1/2 inch long. Small, ovoid, female cones are purple, turning brown at maturity. This is a cold weather tree, prefering moist, well drained, alluvial soils. Several cultivars available. Native from Labrador to Alaska, south into Wisconsin and in the mountains.
