Sedum cyaneum 'Sachalin'
The grey that flowered pink 🌸
- Crassulaceae
- Deciduous perennial
- Blue-grey foliage
- Pink flowers
- Exceptional cold hardiness
Sedum cyaneum 'Sachalin' spreads into a dense mosaic of rounded fleshy leaves. Blue-grey colour meets purple reflections and dark-red stems, producing a low composition with an almost metallic finish.
Toward late summer, pink-to-purple clusters of small star-shaped flowers rise above the cool foliage and transform the entire display. Seasonal change, a naturally spreading line and exceptional cold hardiness make it a distinctive choice for collections, rock gardens and bright outdoor positions.
What makes it special
Cool foliage and dark stems act as a quiet background for a warm star-shaped flower display.
A pink cloud in late summer
Numerous small flowers gather into flat clusters that illuminate the low foliage.
Seasonal change with purpose
Stems naturally retreat in winter and return from the base, providing a true annual cycle rather than a static display.
Why you will love it: it combines an unusual colour palette, generous flowers and remarkable hardiness in a low succulent with four-season character.
In your spacePlacement & plant pairingsWhere it looks its best and which plants complement it
Where it looks its best
Show it on a bright terrace, in a rock garden or at a border edge where stems can spread freely. Grey stone, dark ceramic and natural wood suit its cool palette.
Plants that complement it
Combine it with hardy perennial succulents of a similar seasonal rhythm, using separate pots where water management differs.
- Sempervivum tectorum — persistent geometric rosettes maintain structure while the Hylotelephium rests.
- Orostachys iwarenge — silver rosettes and unusual flowers continue a cool Asian aesthetic.
- Sedum spurium — a low mat and warmer leaves add textural continuity with colour contrast.
Care at a glance
Light
Morning sun to full light, with afternoon protection in the hottest Greek regions.
Water
Moderate water during active growth as the upper zone dries, much less during winter dormancy.
Climate
Exceptionally cold hardy, but requiring airflow and rapid drainage against summer damp.
Pets
No established indication of serious toxicity, though ingestion by children or pets should be prevented.
For this plant
Substrate & nutrition
Detailed careComplete care guideLight, drying cycle, climate, substrate and nutrition in detail
Light and position
In a mild climate it prefers abundant light and direct sun. Under Greek summer heat, morning sun and bright afternoon shade preserve the glaucous foliage better.
Watering correctly
During spring and summer growth, water as the upper zone dries without imposing prolonged drought. Reduce water substantially after stems become dormant.
Air and humidity
Moving air is important around the low mat because dense stems can retain moisture. Avoid standing water and remove dead material after winter.
Temperature and seasonal rhythm
It is highly frost hardy and needs winter cold for normal dormancy. In Greece, prolonged summer overheating is a greater challenge than winter.
Substrate
Use a free-draining mix with mineral components but slightly more organic matter than for a desert cactus. Roots need moisture during growth without saturation.
Feeding and repotting
A small dose of balanced fertiliser with low-to-moderate nitrogen in spring is sufficient, with one further dilute application before flowers if growth is strong. Divide or repot as shoots begin.
Botanical identityIdentity & natural originAccepted name, origin of the form and natural distribution
Accepted botanical placement
The accepted name is Hylotelephium cyaneum (Rudolph) H.Ohba in Crassulaceae. Sedum cyaneum Rudolph is the historical basionym that remains common in trade.
The cultivar ‘Sakhalin’
The Royal Horticultural Society records the selection as Hylotelephium cyaneum ‘Sakhalin’. ‘Sachalin’ in the product title is an older transliteration of the same geographic name; no original selector is widely documented.
Eastern Siberia and the Russian Far East
The species is native to eastern Siberia and the Russian Far East, including Sakhalin Island, in subalpine to subarctic rocky meadows with cold winters.
From natural habitat to home care: winter dieback protects renewal buds below the surface, while fleshy leaves exploit the short growing season. In a pot it needs winter dormancy, cool roots and steadier summer moisture than a desert cactus, always with drainage.
Greenleaf for Plant NerdsScientific details nobody asked forBotanical details for anyone who wants to know what lies behind the plant’s appearance
Hylotelephium was separated from Sedum
Species in this group carry distinct morphological and evolutionary traits, including clearer stems and dense corymb-like inflorescences.
It is a deciduous succulent
Above-ground stems complete their cycle and disappear in winter, while living underground buds begin new growth in spring.
Cool colours are not static
Surface wax and anthocyanins influence grey-blue and purple shades, which change with light and temperature.
Flowers are arranged for many pollinators
Numerous small five-parted flowers gather into flat inflorescences, creating an accessible landing surface for insects.
Frequently asked questions
Useful answers about placement, watering, seasonal behaviour and the plant’s distinctive traits.
01Is it Sedum or Hylotelephium?
The accepted name is Hylotelephium cyaneum. Sedum cyaneum is the historical synonym still widely recognised.
02Why are Sakhalin and Sachalin both used?
They are two transliterations of the same name. Current international spelling and the cultivar record use ‘Sakhalin’.
03Does it disappear in winter?
Above-ground stems are deciduous and retreat normally. The plant remains alive at the base and returns in spring.
04Can it tolerate frost?
Yes, it is exceptionally hardy when roots drain correctly. Under Greek conditions, summer overheating requires greater attention.
05When should it be watered?
During active growth as the upper zone dries, without prolonged dehydration. It needs much less water during winter dormancy.
06What fertiliser does it need?
A small balanced spring dose and, under vigorous growth, one further dilute application before flowering.
