A Compact Dwarf Conifer with Brilliant Blue-Silver Foliage
Juniper Blue Star is an outstanding compact evergreen conifer that creates stunning focal points with its brilliant blue-silver foliage and perfectly rounded form. This exceptional dwarf cultivar of Chinese Juniper is prized for its incredibly slow growth rate and striking needle-like foliage that maintains its vibrant colour throughout the year. Ideal for smaller gardens, rockeries, and container displays where space is limited but maximum visual impact is desired.
Brilliant Blue-Silver Foliage: Dense clusters of sharp, needle-like foliage in stunning blue-silver tones that remain vibrant throughout all seasons, creating exceptional year-round colour.
Perfect Compact Form: Naturally forms a dense, rounded mound typically reaching 80cm-1m in height and spread after 10-15 years, requiring no pruning to maintain its shape.
Extremely Slow Growth: Very slow growth rate of just 2-5cm per year ensures the plant remains compact and in perfect proportion for decades.
Dense Branching Structure: Incredibly dense, compact branching creates an almost cushion-like appearance that provides excellent textural interest.
Exceptional Hardiness: Outstanding cold tolerance and adaptability to various growing conditions makes it suitable for challenging garden situations.
Position: Thrives in full sun where the best foliage colour develops. Tolerates partial shade but may become less compact with reduced light.
Soil Requirements: Extremely adaptable to most soil types including poor, sandy, or clay soils. Excellent drainage is preferred but not essential.
Hardiness: Fully hardy to -20°C or below (zones 4-8), making it suitable for even very cold climates and exposed positions.
Drought Tolerance: Exceptional drought tolerance once established, requiring minimal watering even during extended dry periods.
Urban Tolerance: Excellent tolerance of urban pollution, making it ideal for city gardens and roadside plantings.
Planting Time: Can be planted year-round, though spring and early autumn provide optimal establishment conditions.
Spacing: Allow 1-1.5 metres between plants for mass plantings, or use as individual specimens with adequate space to appreciate their form.
Soil Preparation: Requires minimal soil preparation due to exceptional adaptability. Improving drainage on waterlogged soils will enhance performance.
Pruning: Requires absolutely no pruning due to naturally perfect form. Light trimming can be done if necessary but is rarely required.
Feeding: Very low maintenance, requiring no regular feeding. Established plants thrive in poor soils without supplementary nutrition.
Specimen Planting: Perfect as a standalone feature where its distinctive colour and form create striking focal points.
Rock Gardens: Ideal for rock gardens and alpine collections where its compact size and drought tolerance are perfectly suited.
Container Growing: Excellent for containers, troughs, and raised beds where its slow growth and compact form are particularly valuable.
Ground Cover: Can be mass planted for unusual and striking ground cover effects on slopes or difficult terrain.
Foundation Planting: Outstanding for foundation plantings around buildings where its compact, predictable size is ideal.
The brilliant blue-silver foliage creates stunning contrasts with golden or bronze foliaged plants such as Heuchera 'Caramel' or golden grasses. Pairs beautifully with purple or burgundy plants like Ajuga reptans for dramatic colour combinations. Works well with other dwarf conifers of contrasting colours and textures to create miniature conifer collections.
Spring: Fresh new growth emerges with intensified blue-silver tones, creating beautiful contrast with the previous year's foliage.
Summer: Maintains consistent blue-silver colour whilst providing steady, reliable evergreen structure throughout the growing season.
Autumn: Foliage colour remains stable, providing constant interest as other plants begin to fade or change colour.
Winter: Peak visual impact with brilliant blue-silver foliage creating stunning contrast against snow or winter landscapes.
The perfectly rounded form and compact size make it exceptional for formal garden designs, Japanese-style gardens, and contemporary landscapes. Its predictable growth pattern makes it ideal for situations requiring long-term planning and consistent appearance. The striking colour works equally well in traditional cottage gardens and modern architectural settings.
Once established, this juniper requires virtually no maintenance, making it perfect for low-maintenance gardens. In very wet conditions, ensure adequate drainage to prevent root problems. The plant's natural form is so perfect that any pruning is usually unnecessary and may spoil its appearance. Container specimens may require occasional watering during extended dry periods but are otherwise extremely self-sufficient.
This exceptional dwarf conifer offers gardeners the perfect combination of stunning visual impact, zero maintenance requirements, and predictable growth, making it an outstanding choice for anyone seeking a reliable, beautiful, and long-lasting garden feature that will provide decades of enjoyment.
Buying Conifers from Jacksons Nurseries
Unlike many garden centres, supermarkets and some nurseries here at Jacksons Nurseries we sell the majority of our stock all year round. Our stock is for the most part grown outdoors making it far hardier than those grown under glass and/or only sold ‘In Season’.
Here at Jacksons Nurseries we would favour a hardy outdoor grown plant every time. They are far less likely to suffer from the shock of being planted in colder conditions and they will begin to establish more rapidly the following spring. This can mean that they don’t look like a ‘picture perfect’ plant when purchased out of season but with the correct care and a little time you’ll have a wonderful plant to enjoy for many years to come.
Availability: Stock availability figures are provided as a guide only. There is a delay between orders being placed and the plants being gathered by our pulling team. During this time it may be possible for a member of the public to purchase these plants from our Garden Centre, while this is rare it is a possibility and we will notify you of any problems as soon as possible. This figure may also include plants that have not yet be flagged as unsaleable.
Pre-order: Pre-order times are given as a guide only and may vary dependent on the growing season. Orders containing Pre-ordered products will be shipped as a single order when all items become available. Large orders may be part shipped, please contact us on 01782 502741 or email sales@jacksonsnurseries.co.uk.

Most species of conifer are evergreen, but there are a few deciduous varieties. Some varieties of conifer are good for privacy, as they make excellent hedges. Some are also good for ground cover. They usually have scale-like leaves or needles, and bear iconic cones.
Planting and Conditions
Conifers can be planted throughout the year, but it is best to plant them in the late autumn or winter, as long as the ground is not frozen or waterlogged. Most conifers are frost proof to an extent and hardy, so they will be able to establish well throughout cooler weather.
They should be planted in full sun or partial shade, and are tolerant of most soil types, but will benefit from having compost or manure tilled into the soil prior to planting.
Conifers also need decent draining, so do not plant them in very heavy clay soil or else you will risk drowning the plant.
A hole no less than 1m across and 25cm deep should be dug when planting your conifer. Add organic material such as compost or manure to the hole, and fill it in carefully so that you don’t damage the roots.
Aftercare and Pruning
Unlike other hardwood plants, conifers need very little pruning. However, if green branches appear in trees with coloured or variegated foliage, these should be pruned more often.
Dwarf conifers are not actually dwarf, but are just slower growing. They will eventually become larger and could outgrow their space. This is fairly common with most conifers as they grow, and they can be replaced when it happens. However, their size can be controlled to some extent by pruning and trimming them.
A few conifers such as yew and Thuja, can be pruned hard and will regrow. Most conifers will not regrow from old wood if you prune into it, so take care.
Conifers can be pruned from spring through to late summer.
Newly planted conifers need very careful watering during the initial stages. They are drought proof once established and should not need too much watering, but they are very vulnerable to stress from drought if they are not watered thoroughly.
Removing weeds as soon as they appear is a good way of ensuring that valuable moisture is not lost. Mulching also reduces moisture loss from the top layers of soil.
Potential Issues
Plants can suffer from nutrient deficiencies. Overly acidic or alkaline conditions, dry spells and waterlogging can make it very difficult for plants to extract the right nutrients, and sometimes the soil doesn’t have the right nutrients to start with.
Depending on which nutrient is deficient, mulching, using compost or using a spray enriched with the right nutrients is the remedy to this common ailment.
Brown patches may occur on conifers. There are a number of causes; pests such as the cypress aphid and scale insects can be treated with sprays and foliage removal. Parasitic wasps can also be brought into greenhouses as a biological control for removal of scale insects.
Establishment problems can also occur in young or newly planted conifers. Larger specimens will experience more problems establishing, and will require much greater aftercare than younger specimens. Watering the plant well, but not excessively, and not planting it too deeply should help it to establish better.
Never spray with fertilizer or feed during hot, bright weather or you will risk scorching the leaves. Spray in overcast weather instead.
Root rot can occur when the plant is getting too much water. To remedy this, increase drainage around the plant.
Honey fungus could also occur as a result of waterlogging, or if it is already present on the plant or in the garden. It is the most destructive fungus in Britain, and unfortunately the only treatment is evacuation and burning of affected plant material.
Be sure to extract stumps and roots, as the rhizomorphs that grow during a honey fungus infestation cannot survive in soil when detached from infected material.
