-
Canadian juniper is a naturally occurring native variety of needled evergreen shrub, groundcover, or small tree in the Cupressaceae (cypress) family. The genus name Juniperus means juniper in Latin and the species communis means common. This low-growing juniper that is very tolerant of adverse conditions with the exception of heat and humidity, and is hardy through several USDA Zones from 2-6.
Plant in the full sun in dry well drained soils. It grows to a mature height of 3 to 6 feet with spreading trailing branches up to 12 feet. Gray green needles are awl shaped and stiff giving the shrub a prickly feel. Though the small cones of female plants of this dioecious species resemble berries, they are not true fruits. However, they have a pungent flavor and are used in cooking
Drought and dry soil tolerance is good after it is established and it is also quite disease and insect tolerant. This plant succeeds in urban conditions being air pollution tolerant. It is extremely tolerant of cold temperatures, but due to heat and humidity intolerance, these junipers are not widely successful below Zone 6.
It has a broad, low, vase-shaped form and ascending branchlet tips which is attractive as a specimen plant in the landscape or as foundation plants. The attractive foliage lends winder interest to the landscape.
Insects, Diseases, and Other Plant Problems: No serious problems. Borers, bagworms, mites, midges, and scale are occasional insect problems. Juniper blight can affect any member of this genus.
The Clemson Cooperative Extension Home and Garden Information Center has a factsheet on common juniper diseases and insect pests.
