The crown of this species is conical, straight and bright green. Its greyish, smooth and fibrous bark tends to shed. The needles of this conifer are arranged in a spiral. Its male yellowish brown catkins, as well as its greenish female catkins are located at the ends of its branches. Its cones are round and brownish at maturity and after a year bear about thirty slightly overlapping scales. White and yellow bumps underneath the scales seasonally release pollen grains.

Growing conditions
This species thrives in sun or slight partial-shade sheltered from the wind. It requires soil rich in humus that is well-drained, deep and slightly acid.
Use
