General Description

The dwarf black spruce, 'Nana' is a very slow-growing evergreen shrub that becomes a broad ball when mature. It is a native of northern North America, from Alaska to the northernmost reaches of the United States. This is a boreal tree species that is best in cool, moist soils. The short needles of 'Nana' are four-sided and silvery blue-green to plain green.

Grow dwarf black spruce in full sun and neutral to acidic soil that is rich and friable but has good drainage. Amazingly cold tolerant and never needing pruning to form the rounded shape, it is excellent in shrub borders, foundation beds and small rock gardens. It perhaps is a great alternative to boxwoods in regions with bitter cold and windy winters.
