More Information: 

Size& Form

30 to 50 feet high and 20 to 30 feet wide.
The tree is very narrow and  conical to spire-like with descending branches. Lower limbs sweep the ground.

Tree & Plant Care

Does best in cold northern climates.  It may be stressed in warm summers or below zone 6 temperatures.
The shallow, spreading root system benefits from a 3-4” layer of organic mulch.
Spruce need very little in the way of pruning.
All evergreens experience seasonal needle fall in autumn.  The interior, older needles turn brown and drop. 

Disease, pests, and problems

No serious disease or insect problems but needle rusts and cankers can occur.
Due to its shallow root system, black spruce is prone to wind throw (uprooting by wind).

Native geographic location and habitat

Native to northern North America, from Newfoundland to Alaska, Pennsylvania, Minnesota and central British Columbia. In its more southern range it is found growing around bogs and swamps. 

Attracts birds & butterflies

Twigs, leaves and seeds are important wildlife food. Very valuable as nesting sites for birds. 

Bark color and texture 

Bark is dark gray, thin and scaly.  As bark breaks into scales, the inner green bark is revealed.

Leaf or needle arrangement, size, shape, and texture

Blue green, stiff needles are attached singly to the stem, paler underneath. 

Fruit, cone, nut, and seed descriptions

The cones are the smallest of all of the spruces, rouned to spindle-shape, dark purple ripening red-brown, produced in dense clusters in the top of the tree. Cones are known to persist for several years.
