Description
Dianthus amurensis 'Siberian Blues' is a robust, hardy perennial that forms neat bluish-green mounds covered with masses of lavender blue blooms all summer long. Charming and easy-going, it looks stunning in the foreground of blue and purple themed flowerbeds. This sun-loving plant is tolerant of drought and limestone.
Dianthus amurensis 'Siberian Blues' is a small perennial that belongs to the Caryophyllaceae family. It is native to the valleys along the Amur River in eastern Siberia. Fast-growing and cold-hardy, one plant is enough to cover half a square meter of ground. It forms dense mounds, measuring about of 40 cm in all directions. The light green, tiny, opposite, linear leaves are evergreen. This first-year flowering plant displays simple, lavender flowers with a speckled brown eye from July through till late Autumn.
This prolific bloomer is ideal for rock gardens or patios, and can be very useful for underplanting roses and other summer flowering shrubs. From July to September, its delightful lavender blooms combine well with Phlox 'Amethyst' and Sedum 'Karfunkelstein'. Like most Dianthus species, it is drought tolerant. In dry soil, it can be grown alongside Cerastostigma plumbaginoides, Aster ericoides, A. turbinellus, Salvia x jamensis or S. microphylla etc.

Planting and care
Sow from February to June (or September-October) on the surface of light, moist sowing mix and cover with a fine layer of compost or vermiculite. Place in a propagator or polythene bag and keep in a light room at a temperature of 15-20°C until germination (generally 14 to 30 days). Make sure the soil stays moist but not waterlogged. When the seedlings are strong enough to handle, transplant them into pots. When all risk of frost is over, plant them out in a sunny location, in poor to ordinary soil. Make sure to leave about 30 cm between each plant.
Alternatively, direct sow in spring when frosts are no longer to be feared. Scatter the seeds in loose, well prepared soil, cover slightly and keep moist.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
The flowering period indicated on our website applies to countries and regions located in USDA zone 8 (France, the United Kingdom, Ireland, the Netherlands, etc.)
It will vary according to where you live:- In zones 9 to 10 (Italy, Spain, Greece, etc.), flowering will occur about 2 to 4 weeks earlier.
- In zones 6 to 7 (Germany, Poland, Slovenia, and lower mountainous regions), flowering will be delayed by 2 to 3 weeks.
- In zone 5 (Central Europe, Scandinavia), blooming will be delayed by 3 to 5 weeks.
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The planting period indicated on our website applies to countries and regions located in USDA zone 8 (France, United Kingdom, Ireland, Netherlands).
It will vary according to where you live:
- In Mediterranean zones (Marseille, Madrid, Milan, etc.), autumn and winter are the best planting periods.
- In continental zones (Strasbourg, Munich, Vienna, etc.), delay planting by 2 to 3 weeks in spring and bring it forward by 2 to 4 weeks in autumn.
- In mountainous regions (the Alps, Pyrenees, Carpathians, etc.), it is best to plant in late spring (May-June) or late summer (August-September).
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
