Velvet rather than scales
Short, sickle-shaped juvenile leaves create a soft surface unlike the flat sprays of mature false-cypress foliage.

Round, compact, quietly impressive 🌿
Family: Cupressaceae · Pot diameter: 19cm · Height: 25–30cm
Chamaecyparis ‘Blue Planet’ is the small silver-blue sphere that makes a planting scheme look considered at once. Very short, softly curved needles knit into a dense crown with a clean, full outline and a velvety surface. In a pot, rock garden or the front of a border it provides steady colour, calm geometry and fine texture through all twelve months, with the quiet polish of a living design object.
Its small, beautifully rounded presence brings instant balance to combinations of gravel, stone and broad-leaved plants, while the silver-blue colour lifts even the calmest green palette. It looks equally elegant on its own in a carefully chosen pot or repeated along an entrance, remaining a steady, well-shaped point of interest in every season.
This cultivar brings together a naturally compact scale, dense branching and blue foliage that remains decorative without relying on flowers.
Short, sickle-shaped juvenile leaves create a soft surface unlike the flat sprays of mature false-cypress foliage.
Dense, even side shoots build the rounded outline naturally instead of depending on shearing.
White stomatal bands and the leaf arrangement keep the cool colour visible around the whole crown.
Why you will love it: it gives year-round blue structure in a genuinely small, slow form that fits where a conventional conifer would quickly overpower the design.
Use it as a solitary low accent in a rock garden, trough or front border. Give sun or bright partial shade, free drainage and enough clear space for the round outline to remain visible.
Low broad leaves and arching ribbons make its still, spherical geometry more expressive.
Sun or bright partial shade; protect from fierce afternoon heat in hot districts.
Water deeply as the surface begins to dry; never keep the roots continuously saturated.
Cold hardy to around USDA 5b, but appreciates a cool root and shelter from drying winds.
For ornamental use only; discourage chewing or swallowing foliage and wood.
Give it abundant light and good air circulation. Deep shade makes the crown sparser and dulls the blue colour.
Check the growing mix with your finger and water thoroughly as soon as the top layer dries. Let all excess water drain away.
Use a loose, organic but sharply drained mix, preferably slightly acidic to neutral.
One light application of slow-release fertiliser in spring is enough. Overfeeding opens up its naturally compact shape.
On a south-facing or very warm balcony, shade the pot and avoid the combination of scorching afternoon sun and dry air.
The cultivar withstands severe cold when the soil around its roots drains well. In a pot, protect the root ball above all from prolonged freezing.
Remove only dry or damaged tips. Do not cut deeply into bare old wood, as it does not regrow reliably from there.
Some brown foliage inside the crown may be part of normal renewal. Widespread browning, however, calls for a check of drainage, drought stress and mites.
Short radial shoots create a small dense rounded plant.
Successive short side shoots thicken the surface and strengthen the rounded outline.
After ten years the crown reaches about 30cm in height while remaining softly irregular rather than machine-perfect.
Numerous short branches form a dense, softly irregular sphere; the surface is made from curved juvenile needles, not clipped scale sprays.
The useful change is developmental rather than seasonal: an evergreen sphere becomes denser very slowly through time.
What to expect after planting: During the first year, expect mainly root establishment and small new tips. The characteristic compact sphere fills out slowly and should not be rushed with excessive fertiliser.
Chamaecyparis pisifera ‘Blue Planet’ did not result from a known cross. Pieter van den Dool selected it in the Netherlands after spotting a naturally differentiated branch on the older Chamaecyparis pisifera ‘Boulevard’. It stood out for its lower stature, denser branching and lower susceptibility to fungal disease.
Van den Dool Cultures introduced the selection in 2017 and presented it at that year’s Polish Plant Novelties competition, where it was described as reaching about 30cm high after ten years. Its slow, compact character soon made it especially useful in small gardens and containers.
Prominent stomatal bands on the underside reflect light and strengthen the overall silver-blue colour.
Shorter growth and closer branching give ‘Blue Planet’ its compact rounded character, setting it apart from the larger, looser parent selection.
The six most useful answers before choosing its position and care routine.
No. This is an extremely slow dwarf selection, recorded at about 30cm after ten years.
No. Dense radial branching makes the rounded form naturally; hard shearing damages its soft texture.
Insufficient light can dull the blue. Move gradually to a brighter position without exposing a stressed plant to sudden fierce heat.
Yes, provided the pot drains freely and the root ball is never allowed to bake dry or sit in water.
Avoid it. False cypress does not reliably reshoot from leafless old wood.
Some shaded interior shedding is natural; extensive browning points to drought, waterlogging, drying wind or heat around the pot.
