Flowers/fruit: Monoecious. Fruit a woody cone; short-stalked; 2" to 3" long; ovoid; purple-green to purple-brown when mature; thick, non-pointed scales; can remain closed on the tree for up to 3 years; scales do not open when ripe, rather seeds are released by animals (birds, squirrels) pulling off scales; large, wingless, edible seeds.

General: Native to mountains of central Europe and portions of Asia; not Utah. Narrow, pyramidal tree when young, growing fairly slow and not getting too big (up to 30' tall). Does well on a variety of site but prefers well-drained soils. Very shade intolerant.
Landscape Use: Uncommon in Utah. I have seen a young tree doing well at the Utah Botanical Center Arboretum in Kaysville. Good tight canopy that does not get too big for landscape. Zones 3-7.
Cultivars: 'Columnaris', 'Stricta'.
