More Information

Native Geographic Location and Habitat

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

Bark Description

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

Leaf Description

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 Description

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

Fruit Description

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.

Care Knowledge

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.

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.

Cultivars

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.
