General Description
The black spruce is an elegant evergreen tree that is spire-like with drooping branches that upcurve like eyelashes at their tips. It is a native of northern North America, from Alaska to the northernmost tier of the eastern United States. Often found growing in cool, moist soils, it has a shallow root system and is easily toppled by winds. This is a boreal species.
The needles of black spruce are four-sided, shiny and dark blue-green. The spry branches are relatively short, angle downward and then gracefully curve upward at their tips. Each spring, both male and female cones appear on the tree, but only the latter persist. These attractive, pendant, female cones are initially blue-black and change to dark red and finally to cinnamon brown, maturing in late fall. Cones and dead branches tend to linger on this gray-brown trunked tree for years.
Grow black spruce in full sun and neutral to acidic soil that is rich and friable but has good drainage. It is a slow growing spruce and since it does have a shallow root system it is best located in a wind-protected site or grown in clustered groves.
Selection 'Aureovariegata' has yellow and green needles, while 'Ericoides' and 'Nana' are both excellent for shrub borders, foundation beds and small rock gardens with their dwarf, compact sizes.
