Description

This Sweet William Seed Mix features eye-catching, double blooms with fringed petals. Often two-toned, colours range from white, to pink, purple, crimson or deep red. Very robust and cold hardy, it forms clumps of bluish-green foliage topped with bright blooms 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. This seed mix features plants that 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 double flowers are gathered in flattened clusters, from 8 to 15 cm in diameter, carried at the end of thin yet sturdy stems. Colours range from white to various shades of pink, purple and red, often combining two harmonious tones and changing 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 patio or balcony. Make sure to provide the plants with perfect drainage and a little fertilizer.

Planting and care

Sow the seeds of the carnation 'Poet's Eye' indoors or in a greenhouse, from January to February as a late-flowering annual, or from June to July to see them bloom in spring. Sow on the surface of a good quality, well-drained compost. Place the seed tray in a mini-greenhouse at a temperature of 15-20°C (59-68°F), 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 8cm (3.1in) 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. Leave a distance of 30cm (11.8in) between plants and plant them in any fertile, well-drained soil in full sun.
