Spruce trees are a type of coniferous evergreen tree characterized by their pointed needle-like leaves. They come in various forms, including dwarf spruces and spruce shrubs, making them suitable for different garden landscapes. Tall spruce trees are typically found in coniferous forests.
The genus Picea encompasses 35 species of spruce trees. These evergreen trees are related to other coniferous trees such as pine, cedar, fir, and hemlock.
Some common types of spruce trees include the well-known Norwegian spruce, often used as a popular Christmas tree. Other commonly planted spruces are the Alberta spruce, White spruce, Engelmann’s Spruce, and the Bird’s Nest Spruce, which is a small and low-growing landscaping plant suitable for front or backyards.
Spruce trees are among the tallest conifers found in evergreen forests. For example, the Sitka spruce can reach heights of over 330 feet (100 meters). Dwarf spruce trees and low shrubs are ideal choices for creating specimen trees or evergreen hedges in yards of any size.
In their natural habitat within the cold and temperate climates of the Northern Hemisphere, spruces can live for over 200 years. If you plant spruce shrubs or dwarf spruce trees in your backyard, you can expect them to grow for up to 60 years. Most spruce trees have a slow growth rate, typically around 6 to 11 inches (15 to 29 cm) per year. However, the Norway spruce (Picea abies) and Sitka spruce (Picea sitchensis) are known to have considerably faster growth, averaging 3 feet (1 meter) per year.
As members of the softwood tree category, spruce trees belong to the coniferous species. The wood of spruce trees, similar to soft pine, possesses a gentle quality. However, spruce wood is generally of higher quality and more durable compared to pine wood. This article will discuss the most common types of spruce trees, including providing pictures and scientific names to aid in identification.
Spruce Tree Identification
In this image, we can observe the distinct needles of a spruce tree. Unlike pine needles, spruce needles have four sides, which sets them apart. These needles are firmly attached to the branches and can be easily rolled between your fingers.
Another characteristic feature of spruce trees is their cones. The cones of spruce trees are covered in smooth and thin scales, providing a unique appearance. Unlike the rigid cones of some other tree species, spruce cones are flexible and can be easily bent.
Additionally, spruce trees are known for their bushy branches that point upwards, giving them a distinctive shape.
Spruce Trees Vs. Pine Trees Vs. Fir Trees
Spruce trees can be identified by their square-shaped needles, which easily roll between your fingers, in contrast to the flat needles of fir trees. Unlike the long and soft needles of pine trees, spruce needles are short and stiff. Pine trees typically have needles that grow in bundles of two to seven, while spruce trees have individual needles growing directly from the branches.
The overall shape of a tree can also help distinguish between spruce and pine. Spruce trees have a dense and bushy appearance, with branches that tend to grow upwards. In contrast, pine trees have a more open and downward-growing structure, with minimal foliage. When comparing them to spruce needles, the leaves of cedar trees and Douglas firs are soft to the touch and lack the sharp, jagged texture.
By considering these characteristics, such as needle shape, growth pattern, and foliage texture, one can differentiate spruce trees from pine trees, fir trees, cedar trees, and Douglas firs.
