Fruit, cone, nut, and seed descriptions

White Spruce has the smallest cones of any of the spruces, typically 1 to 2 inches long, cylindrical and pendulous, often clustered near the top of the tree. They are a medium green color throughout much of the summer, and turn brown in autumn and winter. Cones scales are thin, rounded and have smooth margins. A favorite of many birds.

Cultivars and their differences 

Dwarf Alberta Spruce (Picea glauca 'Conica'): 6 to 8 feet high and 4 to 5 feet wide; pyramidal; extremely slow, seldom produces cones. Good for small spaces.

Black Hills Spruce  (Picea glauca var. densata): 20 to 40 feet high and 10 to 20 feet wide, very narrow, dense form, slow growing. Good for space restrictions, screen or windbreak.
