Native geographic location and habitat: 

White spruce is native to Canada and the northwestern United States, in moist, cool climates. 

Bark color and texture: 

The bark is gray to silvery gray and scaly or flaky.

Leaf or needle arrangement, size, shape, and texture: 

The pale green, pointed evergreen needles are 1/2 to 3/4 inch long. They are four-sided, often crowded on the upper surface of the stem. The aromatic needles can persist for three to four years before dropping. 

Flower arrangement, shape, and size: 

Both the male and female flowers are small and insignificant. They are found on the same tree.

Fruit, cone, nut, and seed descriptions: 

White Spruce has the smallest cones of any of the spruces. They are 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. The cone scales are thin, rounded and have smooth margins. It is a favorite of many birds.

Plant care: 

White spruce does best in full sun. It is tolerant of clay soil, but good drainage is a must. The shallow, spreading root system benefits from a 3 to 4 inch layer of organic mulch. Spruce need very little in the way of pruning.

List of pests, diseases, and tolerances: 

Cankers, root rots and needle cast diseases can be a problem on this plant. Bagworm, sawfly and needle miners can be insect problems. It is one of the hosts for eastern spruce gall adelgids.

Dwarf Alberta spruce (Picea glauca ‘Conica’):

A dwarf cultivar, reaching 6 to 8 feet high and 4 to 5 feet wide. It is pyramidal, extremely slow growing and seldom produces cones. It is good for small spaces.

Black Hills spruce  (Picea glauca var. densata): 

This slow growing cultivar reaches 20 to 40 feet high and 10 to 20 feet wide, with a very narrow, dense form. It is good for space restricted areas, as a screen, or a windbreak.
