Spruce trees and shrubs are classified in the genus Picea, which includes 35 species. It's considered part of the Pinaceae family, along with pines, firs, cedars, hemlocks, larches, and a few other species.
A spruce tree can be identified simply by examining its needles. These conifers feature needles attached to the branch by a swollen area, a pulvinus, a joint-like structure that allows extra flexibility and movement. The pulvinus, which resembles a peg, is left behind if a needle drops and is a telling sign that it's a spruce. Another notable characteristic for identification is that, unlike the fascicles (or clustering needles) of pine trees, each pulvinus holds only one needle.
Spruce trees are extremely versatile, with many uses. The narrow, conical growth pattern of many spruce trees makes them excellent choices for landscape use. The shape, of course, means it's a natural choice for Christmas trees, too. Spruce wood is excellent construction lumber, and it has a resonant quality that makes it a favorite for musical instruments.
Here are 12 types of spruce trees and shrubs that can add year-round color to your property.

Bird's Nest Spruce (Picea abies 'Nidiformis')

The bird's nest spruce is a unique cultivar of Norway spruce (P. abies) that takes the form of a round dwarf shrub with an indentation on the top, resembling a bird's nest. It can work well in a container if you wish to have a small evergreen conifer on your patio. This variety grows slowly in the early years, achieving only 1–2 feet of height in the first 10 years.
- Native Area: Northern and central Europe
- USDA Growing Zones: 3–8
- Height: 2–4 feet (can achieve 8 feet over 30 years)
- Sun Exposure: Full

Black Spruce (Picea mariana)
The black spruce does well in wet areas and is native to boreal forest or taiga regions. It's one of the primary hosts for the parasitic eastern dwarf mistletoe (Arceuthobium pusillum). Although the species is a large tree, Nana—an Award of Garden Merit recipient from the Royal Horticultural Society—is a good smaller cultivar that forms a hassock-shaped mound only 1–2 feet high.
- Native Area: Northern North America
- USDA Growing Zones: 3–7
- Height: 30–50 feet
- Sun Exposure: Full

Brewer Spruce (Picea breweriana)
The species name of this tree, breweriana, honors a famous botanist, William Henry Brewer. It's sometimes called the weeping spruce because of the way the branchlets hang down. This is an excellent choice for a specimen tree in your garden as the weeping form gives it unique appeal. A winner of the Royal Horticultural Society's Award of Garden Merit, the Brewer spruce prefers cool, wet winters and dry, warm summers and can be difficult to grow without these conditions.
- Native Area: Northern California, southern Oregon
- USDA Growing Zones: 6–8
- Height: 30–50 feet
- Sun Exposure: Full

Oriental Spruce, Caucasian Spruce (Picea orientalis)
The oriental spruce, also known as the caucasian spruce, can live in a wide variety of soil types but needs to be sheltered from wind. This slow-growing tree works well as a specimen conifer, and it has 1/2-inch needles, which are shorter than most other spruces. If you want one with yellow needles, look for the Skylands, Aureospicata, and Aurea cultivars. Barnes and Nana are dwarf cultivars, while Gowdy is columnar in shape.
- Native Area: Mountainous regions from Caucasus to Turkey
- USDA Growing Zones: 4–7
- Height: 10–35 feet
- Sun Exposure: Full

Colorado Blue Spruce (Picea pungens)
The Colorado blue spruce has blue needles in a range of shades. The Glauca variety is a light blue, and Glauca Pendula is a weeping cultivar. If you want a shorter one, available varieties include Fat Albert, Glauca Globosa, and Glauca Jean's Dilly. This spruce, the state tree of both Colorado and Utah, does well in droughts overall but does need regular watering in hot areas.
- Native Area: Rocky Mountains, south of Montana
- USDA Growing Zones: 3–8
- Height: 30–60 feet
- Sun Exposure: Full

Dwarf Alberta Spruce (Picea glauca 'Conica')
The dwarf Alberta spruce is a unique cultivar of the white spruce, known for its conical shape, soft bright-green needles, and dwarf shrub form. It's a great choice for a Christmas tree and is commonly used for creating spiral shrub topiary and other shapes (it's often seen in planted pots next to a front door). This cultivar was discovered in Alberta, Canada, in 1904 and has since become one of the most popular of all spruces in cultivation.
- Native Area: Alberta, Canada
- USDA Growing Zones: 3–6
- Height: 10–13 feet

Engelmann's Spruce (Picea engelmannii)

The Engelmann spruce was named for George Engelmann, a botanist and physician. Some have considered it a subspecies of the white spruce, sharing its narrow, conical shape. It's the most common spruce in the higher elevations of the Rocky Mountains. Its wood is used in the lumber industry and to make musical instruments, but the tree is not a great landscape specimen in warmer climates. Engelmann spruce trees can live for hundreds of years, achieving towering heights if the growing conditions are favorable.
- Native Area: Western North America
- USDA Growing Zones: 2–5
- Height: 70–100 feet

Norway Spruce (Picea abies)

Commercially, the Norway spruce is grown as a Christmas tree and for construction lumber. It's also often used for making stringed instruments because it resonates well. If you want an unusual specimen, look for the Inversa cultivar, a dwarf weeping variety that's a definite eye-catcher. This species needs soil that drains well, and it will have problems if the soil is too wet.
- Native Area: Northern and central Europe
- USDA Growing Zones: 2–7
- Height: 40–60 feet

Red Spruce (Picea rubens)
Often farmed as a Christmas tree and for wood pulp, the red spruce is upright, oval, and extremely long-lived. It can be planted in areas that receive shade (it's especially tolerant of shade when young), should stay relatively cool, and requires adequate moisture. However, it's susceptible to acid rain and doesn't make a good landscape tree in urban areas. While it's named for the reddish color of its bark, this species is also called the yellow spruce, inspired by the light yellow wood of the tree.
- Native Area: Southeastern Canada, northeastern United States
- USDA Growing Zones: 3–6
- Height: 60–130 feet
- Sun Exposure: Full, Partial

Serbian Spruce (Picea omorika)
The Serbian spruce can tolerate some drought and shade, though it prefers medium levels of moisture in the soil, and it's a good choice for urban landscapes because it resists air pollution. This is one of the better spruce species for hot, humid conditions. Its species name, omorika, is the Serbian word for spruce.
- Native Area: Balkans
- USDA Growing Zones: 4–7
- Height: 50–60 feet (occasionally 100 feet)
- Sun Exposure: Full

Sitka Spruce (Picea sitchensis)
The Sitka spruce, the state tree of Alaska, is the tallest spruce species, capable of reaching higher than 300 feet in the wild. The largest recorded specimen was 318 feet. Although this variety will be shorter in cultivation, make sure there's plenty of room in your landscape because "shorter" can mean that it's still more than 100 feet high.
- Native Area: Alaska to California
- USDA Growing Zones: 6–8
- Height: 50–100 feet or more (300 feet is possible)
- Sun Exposure: Full

White Spruce (Picea glauca)
The white spruce is frequently grown commercially as a Christmas tree, but it also makes a good specimen tree for the landscape or in windbreaks. The needles have a whitish waxy (glaucous) coating, leading to the common name. A naturally occurring variety is the Black Hills spruce (Picea glauca var. densata), which is the state tree of South Dakota. This is an extremely hardy tree once established, but it's somewhat sensitive to urban pollution.
- Native Area: Canada, northern U.S.
- USDA Growing Zones: 2–6
- Height: 40–60 feet
- Sun Exposure: Full, Partial
