Picea glauca var. albertiana 'Conica,' the ubiquitous dwarf Alberta spruce, is arguably the most commonly planted conifer in the nursery trade. It is a slow, conical growing plant with tight uniform branching holding light-green juvenile foliage. After 10 years of growth, a mature specimen will measure 4 feet (1.3 m) tall and two-thirds as wide, an annual growth rate of around 4 inches (10 cm).
