Buds: Hairless, slightly rounded. Pointed outer bud scales do not project beyond the tip of the bud.

Leaves: Needle-shaped, stiff, sharp pointed, shiny, four-sided in cross section, yellow-green to blue-green, often covered with a whitish bloom, 0.5-2 cm long. Spirally arranged in the twig but twisted upwards to crowd the upper side.

Flowers: Small, sexes separate on same tree. Male flowers oval, 1 cm long, rosy red at first, then purplish when shedding yellow pollen. Female flowers about 1.6 cm long at flowering time, erect and oval shaped, consist of many reddish-purple scales. Blooms in June.
