Eastern red-cedar is native to North America. These cold-hardy, adaptable evergreen trees serve many purposes in the landscape, especially in sites that are dry, alkaline or windy. The foliage of scale-like needles is attractive but prickly. In late summer and fall, many junipers have blue-green berry-like fruits, actually modified cones, that attract birds. Because they are quite salt-tolerant, they can be used near roads, driveways, and sidewalks. Eastern red cedar is usually a tree, but there are shrub-sized cultivars available.

Tree & Plant Care
Best in full sun with well-drained soil.
Adaptable to high pH (alkaline) soils.
Tolerant of dry, windy conditions once established.
Prune in early spring.
Disease, pests, and problems
Cedar rusts (cedar-apple, cedar-hawthorn and cedar-quince) and bagworm are common.
Native geographic location and habitat
East and central North America; often found in sunny, limestone outcropping, along fencerows and roadsides.
Bark color and texture
Trees often develop exfoliating reddish brown bark.
Leaf or needle arrangement, size, shape, and texture
Prickly, silvery-blue foliage (needle-like and/or scale-like).
Winter needles often turn a bronzy-green. Some cultivars keep their color all winter.
Fruit, cone, nut, and seed descriptions
Male plants produce small, inconspicuous cones that produce pollen.
Female plants produce berry-like cones that, if pollinated, ripen to a bloomy blue-gray color. Fruit often persist throughout winter.
A favorite for many birds and wildlife.
This plant is a cultivar of a species that is native to the Chicago Region according to Swink and Wilhelm's Plants of the Chicago Region, with updates made according to current research. Cultivars are plants produced in cultivation by selective breeding or via vegetative propagation from wild plants identified to have desirable traits."
Blue Eastern red cedar (Juniperus virginiana 'Glauca'): Narrow, upright, columnar evergreen tree, 20 to 25 feet high and 8 to 10 feet wide. Silver-blue spring foliage turns blue-green in summer. Use as a specimen, in groups, or as an informal hedge.
Blue Mountain (Juniperus virginiana 'Blue Mountain'): Spreading evergreen shrub, 3 to 4 feet high and 5 to 8 feet wide. Blue-green foliage is softer and more needlelike than that of most junipers. Plants of this female cultivar produce berry-shaped cones that, if pollinated, ripen to a bluish color. Use as a foundation plant, in shrub borders, or on slopes.
Canaert (Juniperus virginiana 'Canaertii'): Pyramidal tree, 20 to 35 feet high and 15 to 20 feet wide. Dark green foliage tufted at ends of branches; open crown, attractive bluish-white clusters of fruit; reddish-brown bark exfoliating into long strips. Use as a specimen, in groups, or for informal screening.
Grey Owl (Juniperus virginiana 'Grey Owl'): A low growing, spreading shrub reaching 3 to 4 feet high and 6 to 8 feet wide. Silver-grey foliage attractive all year. A female form that develops attractive blue berries.
