Black spruce grows throughtout Prince Edward Island and is confined mainly to low damp places. In sphagnum bogs it usually is dwarfed to a mere shrub. It is a small tree from 30 to 50 feet in height and from 6 to 9 inches in diameter, although under favourable conditions, it will grow much larger. The trunk is straight with little taper. On old trees the crowns are open and irregular with slender drooping branches which turn up at the ends, while in young trees, the crowns are narrow and symmetrical with short slender almost horizontal branches. The bluish-green appearance of this spruce makes it distinguishable from the other spruces.
