Picea glauca var. albertiana 'Alberta Globe' is a dwarf selection of Alberta spruce with all of the foliage characteristics common to the ubiquitous P. glauca var. albertiana 'Conica' but with a much slower growth rate and a globose shape. After 10 years of growth one can expect a mature plant 16 inches (40 cm) tall and 24 inches (60 cm) wide, a growth rate of just over 1.5 inches (4 cm) per year.
C. Streng Jr. of Boskoop, The Netherlands is credited with the introduction of this cultivar in 1968. It originated as a witch's broom mutation found on a specimen of 'Conica.' This plant is occasionally seen incorrectly listed in the nursery trade as 'Globe' or 'Albertiana Globe.'
