Cultivars/Varieties
'Nana' - This form assumes a dense, globular form when young. In time, it becomes a broad pyramid. The needles are densely set, deep green and have a white line underneath.
'Pendula' - Very popular as a specimen plant with upscale landscapers, this tree has drooping branches that make for a dramatic specimen. The habit is open, with deep green needles that are whitish underneath. 'Pendula Bruns' is a similar selection with an even more strongly weeping habit.
