Picea abies 'Globosa' / Globose Norway spruce

Picea abies 'Globosa' is a dwarf, globose selection of Norway spruce with loose, symmetrical branching and dark-green foliage. After 10 years of growth, a mature specimen will measure 3 feet (1 m) tall and wide, an annual growth rate of 3 to 4 inches (7.5 - 10 cm).

This designation has been used to describe globose forms of Picea abies since the late 1800s. Ernst von Berg (1782–1855) is thought to be the first to use the cultivar name to describe a spruce that originated from a witch's broom selection. In 1939, Murray Hornibrook made the observation that globose seedlings are quite common in cultivation. It with great certainty that plants listed as, P. abies 'Globosa' don't all derive from a single, distinct clone. With that, it's probably best that this cultivar name be relegated to forma-status, i.e. Picea abies f. globosa.
