Description
Sweet William 'Summer Sundae' is a wonderful selection that flowers in the first year from seed. The abundant blooms display a rich array of colours, from white to purple and various shades of pink. Very robust and cold hardy, they form very floriferous clumps of bluish-green foliage in late spring and early summer. Ideal for cutting, this selection is suitable for growing in pots and self-seeds abundantly. Easy to grow in cool, rich, well-drained soil, in full sun or partial shade.
Dianthus barbatus is a biennial plant that belongs to the Caryophyllaceae family. It occurs naturally in temperate regions of Europe and Asia. This cold-hardy plant generally flowers in its second year after sowing. 'Summer Sundae' brings together several fast-growing varieties, producing flowers in the first year from seed. Plants quickly form a very dense basal clump of long leaves with pointed tips, light green to bluish green in colour. They vary in size from 45 to 60 cm tall in full bloom. Flowering takes place in late spring and early summer. The small flowers are gathered in flattened clusters, from 8 to 15 cm in diameter, carried at the end of thin yet sturdy stems. They vary greatly in colour, often featuring two tones and attractive markings. Some plants produce blooms that gradually change colour as they age. Sweet William flowers have a gorgeous spicy and sweet scent, with notes of cloves and cinnamon.
Sweet William is an easy plant to grow, that is very low maintenance once established. Like bellflowers and columbines, it effortlessly fits into any garden. Grow along passageways such as garden paths or near an entrance to fully enjoy its sweetly scented blooms! In flower beds and borders, grow en masse to create beautiful drifts of colour. Dianthus barbatus is suitable for container gardens, in pots on the terrace or balcony. Make sure to provide the plants with perfect drainage and a little fertilizer.

Planting and care
Sow the seeds of annual carnation indoors or in a greenhouse, from January to February for late flowering, or from June to July to see them bloom in spring.
Sow on the surface of good quality and well-drained compost. Place the seed tray in a mini-greenhouse at a temperature of 15-20°C, or in a transparent polyethylene bag until germination, which takes 7-21 days. Keep the compost moist but not waterlogged and do not exclude light.
When the seedlings are large enough to handle, transplant them into 8 cm pots and let the plants grow in cooler conditions. When all risk of frost has passed, gradually acclimatize them to outdoor conditions for 7-10 days before transplanting them outside. Maintain a distance of 30cm between plants, and plant them in any fertile, well-drained soil in full sun.

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.
