Cultivars/Varieties
'Aurea' - The light green needles of this slow-growing tree turn bright yellow in winter, adding color to a bleak landscape.
'Beauvronensis' - An old cultivar, this plant reliably produces a compact, dense mound of needles. It is slow-growing and very broad in habit.
'Fastigiata' (also listed as f. fastigiata) - This is a strictly columnar form that may reach 25' tall and only a few feet wide. It is among the most fastigiate conifers available, but has a tendency to break up under winter ice and snow loads. It may benefit from being tied together. The needles are blue-green. 'Spaan's Fastigiate' is a slower-growing fastigiate form that is less susceptible to breaking up under snow and ice.
'Hillside Creeper' - A groundcover form, this plant grows vigorously to form an undulating carpet of medium green needles. 'Albyn Prostrata' is a similar form with thick, shiny green needles.
'Pumila' - Forming a large upright shrub with a broadly rounded habit, this selection is useful as a hedge or focal point. The needles are blue-green.
'Watereri' - This is a popular cultivar that typically reaches about 10' tall with a dense pyramidal growth habit. The needles are a steely blue color.
