Rocky Mountain Juniper ‘Skyrocket’: A Slim, Evergreen Privacy Screen for Full Sun

There’s a much more attractive option.

An evergreen shrub that copes with full sun can block prying eyes, improve the garden’s microclimate and look genuinely smart at the same time. If you plant thoughtfully, you can avoid artificial privacy screening altogether-and gain a living, year-round green “outdoor room”.

Why a living privacy screen does far more than plastic

Plastic screening, timber panels or fabric sails may hide the view, but they can quickly feel gloomy, get very hot in the sun, and offer neither shade nor habitat. An evergreen shrub brings a great deal more to the table.

“A well-positioned sun-loving shrub protects privacy, cools the surroundings, adds colour and fragrance-and massively enhances the garden visually.”

Evergreens are particularly appealing because they keep their foliage throughout the year. They still form a dense barrier in January, when deciduous hedges have long since become see-through. Many will also take strong sunshine, while adding:

• fragrant flowers in spring or summer
• colourful berries in autumn
• strong structure from twigs and needles in winter
• food and shelter for birds and insects

If you live in a terraced house, have a compact city plot or only a roof terrace, you’ll often need privacy screening that doesn’t eat up precious space. This is exactly where one specific conifer really shows its strengths.

The insider choice: Rocky Mountain juniper ‘Skyrocket’ as a slim privacy wall

Rocky Mountain juniper ‘Skyrocket’ (Juniperus scopulorum ‘Skyrocket’) is one of the narrowest evergreen shrubs widely available. It grows into a dense, upright column that rarely becomes much wider than about a metre-while ultimately reaching around four to five metres tall.

Key characteristics at a glance:

• Growth habit: very upright, columnar
• Height: about 4–5 metres
• Width: roughly 0.6–1 metre
• Foliage: scale-like needles, blue-green with silvery highlights
• Position: full sun, tolerates wind
• Soil: rather dry to fresh, well-drained

In good conditions, it puts on about 30 centimetres a year. Often, just two or three plants are enough to raise a balcony boundary visually or to block a sightline towards a neighbour’s window.

“With just a few specimens, you get a narrow, evergreen ‘curtain’ that screens you off without overwhelming the garden.”

How to plant ‘Skyrocket’ correctly in a sunny spot

Autumn or spring is the ideal planting window. The soil shouldn’t be waterlogged; it’s best when it has drained and isn’t saturated.

• Dig a planting hole at least twice as wide as the rootball.
• Loosen any compacted soil at the base so water can drain away more easily.
• Gently score the rootball so the roots can spread into the surrounding soil.
• Mix the garden soil with a little well-rotted compost-avoid heavy fertiliser applications.
• Water thoroughly after planting, then mulch over the root area.

During the first two summers, ‘Skyrocket’ benefits from extra watering during prolonged dry spells. Once established-and as long as it isn’t sitting in constantly wet ground-it copes well with moderate drought.

Where juniper really comes into its own

This shrub is especially useful anywhere width is at a premium:

• along the edge of a terrace to block views from above or at an angle
• as a green divider between a seating area and wheelie bins
• planted along a boundary line in a terraced-house setting
• in gravel or rock gardens as a strong vertical accent

Its blue-green colouring looks particularly crisp in intense sunshine, and it appears even more pronounced when light hits the needles at an angle. The reddish-brown bark adds pleasant winter colour when much of the garden can look grey.

Other evergreen sun-lovers for colour and wildlife in your screen

Depending on your local conditions and climate, you can add other shrubs to make the screen thicker and more varied.

Simpson’s stopper: fragrance, berries and a bird favourite in mild areas

In places with very light frost, an exotic North American shrub can work well: an evergreen with glossy leaves, white scented flowers and orange-red berries, often used as a hedging plant in its home range. In UK gardens it tends to suit:

• sheltered courtyards
• warm, sunny walls
• large containers on bright terraces

The fruits draw in birds that appreciate the extra food, turning the privacy screen into a small nature project as well.

Viburnum tinus for winter flowers and dense structure

Viburnum tinus, usually sold under its botanical name, grows to around two to three metres and forms a thick cloak of dark green foliage. Its standout feature is flowering in the colder months-often from late autumn through to spring-producing white flower clusters.

This makes it ideal for filling gaps in a juniper “curtain” or for creating a lower tier in front. For instance, placing ‘Skyrocket’ as a back row with Viburnum tinus in front creates a layered, very dense, yet still lively hedge.

Viburnums for graphic form and a blaze of berries

Other Viburnum species-especially Asian types-add striking flower heads and vivid berries. Varieties from China can carry delicate spring blooms, followed later by showy red fruit that birds happily feast on.

How to plan your natural privacy screen in a sunny border

If you want to move away from plastic screening, think beyond height alone-consider light, soil and the effect you’re aiming for. A few practical pointers:

• Distance to the boundary: check the relevant rules and guidance for your area.
• Mix rather than monoculture: combine several species to reduce the risk of disease and gaps.
• Maintenance: juniper needs very little pruning; other shrubs often respond to occasional cutting back by becoming bushier.
• Biodiversity: include berrying shrubs so birds benefit.

If you’re unsure, don’t rely only on the plant label at the garden centre-ask specifically for evergreen varieties that suit full sun. Taking a photo of your terrace or the corner of the garden can make advice far more accurate.

Added benefits beyond privacy

A living screen can noticeably shift the microclimate. Leaves release moisture into the air, bringing gentle evaporative cooling on hot days. Where a plastic sheet once stored heat, you can create a shadier, airier edge that’s simply more comfortable to sit beside.

It can also change how sound carries. Dense shrubs break up noise and absorb some of it, so road traffic or conversations from next door feel less direct-even if you can’t remove the source entirely. The garden comes across as calmer.

Another useful approach is combining permanent planting with movable elements. Once you’ve created the backbone with ‘Skyrocket’ and other evergreens, you can use pots that change with the season-summer flowers, grasses or even small fruit trees in containers. The screen stays stable, while the foreground can evolve.

For families with children or pets, this green curtain can also add a layer of safety: it helps define play areas and stops passers-by seeing straight into private life. The look feels more natural, the atmosphere more relaxed-and the old plastic privacy screen ends up, sooner or later, where it belongs: at the recycling centre.
