A dwarf compact variety of Sweet William with a very wide colour range that makes excellent bedding. Dianthus barbatus 'Indian Carpet Mixed' can be treated either as a biennial or as a half hardy annual. Sown in early spring, it will produce flowers from early summer, usually in around 10 weeks from sowing. Alternatively, grow it as a biennial for blooming in the following spring. This short lived perennial is ideal for cottage garden borders, beds and containers. Height: 15cm (6"). Spread: 30cm (12").

Culinary note: Use the clove like tasting petals for adding to cakes, either for flavour or decorating, suitable for soups, salads and sauces too. For more details about edible flowers click here.


1 packet (400 dianthus seeds) (26574)

Sow Sweet William seeds indoors or under glass from February to May as a late flowering annual, or from June to July for flowering the following the spring. Sow on the surface of a good quality seed compost and gently firm down. Place the seed tray in a propagator at a temperature of 15-20C (59-68F) or seal inside a clear polythene bag until germination which takes 10 - 14 days. Keep the compost damp but not wet and do not exclude light.

When seedlings are large enough to handle, transplant into 7.5cm (3") pots and grow Sweet William plants on in cooler conditions. When all risk of frost has passed, gradually acclimatise to outdoor conditions over 7 - 10 days before planting outdoors after all risk of frost has passed. Plant Sweet Williams at a distance of 30cm (12") apart on any fertile, well drained soil in full sun.

Feed and water Sweet William plants regularly until they are fully established. Deadhead faded Sweet William flowers to encourage more blooms to be produced throughout the summer.
