Junipers are a group of aromatic evergreen shrubs and trees in the Cypress family that are native worldwide in the northern hemisphere. Many varieties are standard elements that are frequently planted in a landscape, such as Juniperus communis ‘Greenmantle,’ a prostrate, spreading Juniper, and Juniperus communis ‘Compressa,’ a conical, dwarf tree. Others delight with their diverse colors, shapes, heights, and textures. Juniperus scopulorum ‘Skyrocket,’ for example, is the narrowest of the Junipers, and is very blue. The young Skyrocket trees stay narrow until approximately seven years old, but become slightly less narrow with age. Others, such as the dark green Juniperus virginiana ‘Taylor,’ are tall and keep their narrow shape, even in maturity. They are ideal for duplicating an Italian Cypress look, but will grow in colder climates. Juniperus chinensis ‘Angelica Blue’ is the bluest of the low-growing, spreading Juniper shrubs, while Juniperus scopulorum ‘Blue Arrow’ is the bluest of the columnar trees.
Junipers come in a variety of shapes that can fulfill specific purposes in a landscape. Some lie flat on the ground with a number of branches spreading outward and are excellent as ground covers. Juniperus chinensis ‘Daub’s Frosted‘, and Juniperus communis ‘Greenmantle’, or Juniperus horizontalis ‘Pancake’ are good examples.
Others are shrubby, with numerous branches extending up from the ground, such as Juniperus chinensis ‘Angelica Blue‘, and Juniperus horizontalis ‘Blue Forest.’ They add interest and fill the space in front of buildings as foundation plantings.
Junipers can also grow in a columnar or pyramidal form depending on the species and variety. Columnar varieties differ widely and have multiple uses depending on their shape, size, and texture. They can function as accent (specimen) plants, entrance trees, as informal groupings, visual barriers at boundaries or borders, and for windbreaks, between windows, at building corners, and as front door sentinels.

This plant is great as a spreading ground cover, over walls or rock gardens, and can also be trained as a topiary tree. It grows to 6”H × 4’W in 10 years at a rate of 3”-6” a year. Greenmantle is hardy to USDA Zones 3 to 9, grows in sun to light shade, and is drought tolerant and deer resistant.
Juniperus communis ‘Hibernica’ (Irish Common Juniper)
Hibernica is a narrow, columnar Juniper with strong, upright branches that resist bending down with snow. It is green to blue-green, and grows 4-6″ a year, reaching 6’H × 2’W in 10 years, becoming more conical and wider with age.

Pancake is hardy to USDA Zones 3 to 8, and grows well in sun to partial shade. It is perfect as a flat, spreading ground cover, and spilling over retaining walls and rock gardens.
Blue Arrow Juniper is one of the cold-hardy choices for those who are seeking a similar look of Italian Cypress. Its blue-green, rope-like foliage emphasizes the narrow, upright branches. Blue Arrow grows best in the sun, is deer resistant, and is hardy in USDA Zones 2 to 8. It is a smaller tree than the Italian Cypress, growing 8” to 10” a year, and reaches a height and width of 7’H × 2’W in 10 years. It is stunning as an entrance tree or as a landscape accent.
Skyrockets are exceptionally narrow junipers with dense blue-green foliage. Since they have such a slender form, Skyrocket plants can be placed close together to make pleasing and effective privacy screens, windbreaks, or hedges. They grow about 12” per year, reaching a height and width of 15’H × 2’W in 10 years. They are hardy to USDA Zones 3 to 8, grow well in sun, and are deer resistant and drought tolerant. Skyrockets are a variety of the native Rocky Mountain Juniper, and are probably the narrowest junipers on the market, although they do become more pyramidal in shape as they age.
Juniperus virginiana ‘Brodie’ (Brodie Eastern Red Cedar)
This popular, dark green Red Cedar has a classic pyramidal form, making it a cold-hardy alternative to the Italian cypress. Its dense, feathery foliage makes it a great barrier or screen, hedge, or specimen tree. Brodie is deer resistant and drought tolerant, grows in full to partial sun, and is hardy to USDA Zones 4 to 9. It grows at a fast rate of 12” to 24” a year and reaches 15’H × 4’W in 10 years. This is a variety of the Eastern Red Cedar, native to the United States east of the Rocky Mountains.
This is a classic columnar evergreen that can substitute in colder climates for the look of the Italian Cypress. It has feathery, blue-green foliage, and is an excellent entrance tree or with just the right dimensions to block a vertical pipe or downspout. The Taylor Juniper likes sun, it grows 8” to 10” per year, and attains a size of 10’H × 6’W in 10 years, remaining slender throughout its growth. Taylor is hardy to USDA Zones 4 to 8 and is deer resistant. Junipers are very easy to grow since they are poor soil tolerant, heat and drought tolerant, and deer resistant. The thing they don’t like is wet feet. Junipers don’t do well and tend to get root rot when their roots are left in waterlogged soil. And please don’t plant junipers near apples, crabapples, hawthorns, quince, or pear. They are susceptible to cedar-apple rust and related rusts that require two hosts — junipers and apples or other trees in the rose family.
