What does the legal guarantee mean for plants?
The legal guarantee concerns the plant’s conformity at delivery. It is not a guarantee of survival or growth for two years. Each issue is assessed taking into account the nature of the plant, its care and the conditions in which it is kept. Your statutory rights remain unaffected.
Juniperus communis ‘Compressa’
Rock, wind, cold? Bring them all on ❄️
- Very narrow column
- Silver-blue needles
- 0.5–1m mature height
- RHS AGM 1993
Juniperus communis ‘Compressa’ is a miniature common juniper shaped like a tiny, finely carved spire. Short upright branches press close to the central axis, wrapping it in dense grey-green to silver-blue needles and giving the crown the crisp outline of a slender candle. Its cool colour and precise silhouette bring quiet architectural presence to even the smallest planting.
Placed among rounded cushions, trailing stems or pale stone, ‘Compressa’ becomes a small exclamation mark that sharpens the whole composition. It is equally striking in a trough or alpine bed, where its compact line creates a strong vertical accent, rhythm and a sense of scale without crowding its neighbours.
Juniperus communis ‘Compressa’ received the Royal Horticultural Society Award of Garden Merit in 1993.
What makes it special
A very slow column of short upright branches and densely packed silver-blue needles.
Silver along every needle
A bright stomatal band on the upper surface lends a grey-blue cast to the green foliage.
Naturally dense apex
Short annual extension fills the cone without routine clipping.
Why you will love it: it brings permanent upright precision to a rock garden, small border or container while leaving the surrounding space open.
In the garden & on the balconyPlacement & plant combinationsNarrow silver-blue column · sun to light shade · mature spread 0.1–0.5m
A small upright accent
Use it in a rock garden, gravel composition, alpine bed or deep container where its narrow line can be seen in full. Keep roughly 40–50cm from spreading plants so they do not cover its base and air can move between the needles.
Pink and amber
Cool needles stand out beside low pink flowers, warm copper seed heads and fine blue foliage.
- Erica carnea — winter pink at the base with a shared preference for drainage.
- Hylotelephium ‘Herbstfreude’ — warm flat flower heads balancing the narrow cool line.
- Festuca glauca ‘Elijah Blue’ — a low blue tussock repeating the colour in a softer form.
Care at a glance
Light
Full sun for a dense silver-blue crown; it tolerates light shade but not deep shade.
Watering
Water regularly until established, then water deeply but less often, always allowing the soil to drain.
Climate & hardiness
Exceptionally cold hardy at RHS H7; in a hot Mediterranean summer avoid reflective heat and a permanently dry root zone.
Safety
Not intended for consumption; the sharp needles can cause mechanical irritation, so wear gloves.
Detailed careComplete care guideEight practical points: Position, Watering, Soil, Feeding, Pruning, Winter colour, Container growing, Safety.
Position
Give sun to light shade and clear air movement, away from a wall reflecting intense summer heat.
Watering
Water deeply while establishing and whenever the root zone dries; do not keep the growing medium permanently wet.
Soil
Use freely drained, sandy or gravelly soil that is poor to moderately fertile and ranges from acidic to alkaline.
Feeding
Apply only a light evergreen feed in spring if growth is weak; excess nitrogen loosens the column.
Pruning
Keep the natural leader and remove only dead or broken tips; never cut deeply into bare old wood.
Winter colour
A slight winter change in colour can be normal. Before removing a browned shoot, check its needles and buds; flexibility alone does not establish that it is healthy.
Container growing
Use a deep pot with large drainage holes, refresh the surface compost and shield roots from overheating.
Safety
Wear gloves and long sleeves while handling it because the short rigid needles prick easily.
Development over timeHow the little silver column growsThree stages from fresh green tips to a dense narrow crown and faint winter bronzing.
Fresh short tips
New green sections extend the apex and lateral branches by a small amount.
Dense silver-blue column
Needles harden and short upright branches fill the narrow outline.
Deeper winter colour
Evergreen foliage darkens or bronzes slightly before spring extension begins.
Mature form & dimensions
Indicative mature formHeight 0.5–1 mSpread 0.1–0.5 mDense short upright branches
Very short ascending branches stay close to the central axis. Dense pointed needles form the narrow canopy.
Form through time
Young growthShorter branches and bright new tips
Winter appearanceDense needles on short upright branches
Evergreen foliage remains through winter. Its shade varies with temperature and lighting.
What to expect after planting: Annual change is small: a few new tips add height and density without greatly increasing the spread. The column becomes fuller with time and retains its needles through winter.
History & originCultivar originAn old selection with exceptionally slow growth
‘Compressa’ is one of the long-established dwarf selections of common juniper, Juniperus communis. Murray Hornibrook included it in his work on dwarf and slow-growing conifers, discussing its behaviour in cultivation.
Historical horticultural descriptions emphasise how slowly its small, dense column develops: it can remain very short even after many years. These later accounts do not establish the first record or the original raiser with certainty.
In 1993 it received the RHS Award of Garden Merit.
Greenleaf for Plant NerdsScience nobody asked forBotanical details for anyone curious about what lies behind the plant’s appearance
Three needles at a node
Juniperus communis usually bears its needles in whorls of three. A broad pale stomatal band runs along their upper surface, containing the microscopic openings involved in gas exchange.
A berry-like cone
The fleshy, berry-like structures of female junipers are cones with fused fleshy scales. They are not botanical berries like grapes. Their presence depends on the sex and reproductive maturity of the individual plant.
Frequently asked questions
Six specific answers about identity, mature size, growth, light, pruning and the winter colour of Compressa.
01Is this a separate species of juniper?
It is a cultivar of common juniper, Juniperus communis, selected for its very narrow form and exceptionally slow growth.
02How large does it become?
Allow about 0.5–1m in height and 0.1–0.5m in spread, with very slow growth and natural variation by site and age.
03Does it grow quickly?
No. It adds only short increments each year and needs time to develop the density of a mature column.
04Sun or shade?
Sun produces a denser, more silver-blue crown. It tolerates light shade but opens and becomes greener in deep shade.
05May I clip it to keep it narrow?
It usually needs no clipping. Remove only stray young tips and never cut deeply into bare old wood.
06Why did its colour change in winter?
Cold weather can darken or lightly bronze the needles, followed by fresher colour as spring growth develops. Entirely dry foliage or brittle shoots need closer inspection; flexibility alone does not confirm that a branch is healthy.
