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 (30 dianthus seeds) (26317)

Sow February to April. Germinate at 18-20C (64-68F) on the surface of a good free draining, damp seed compost. Do not cover the seed. Place in a propagator or seal container inside a polythene bag until after germination which usually takes 7-21 days. Do not exclude light, as this helps germination.

Transplant seedlings when large enough to handle into trays or 7.5cm (3in) pots. Grow on in cooler conditions for 10-15 days before planting out after all risk of frost, 30cm (12in) apart.

Prefers a rich, well drained soil in full sun.
