This new interspecific hybrid brings the strongest shade of red we’ve seen in a Sweet William. The pillar-box red flowers make an exciting display in summer beds and borders, gently perfuming the air with their sweet, spicy fragrance. Dianthus barbatus 'Rockin' Red' is a reliable hardy perennial that puts on a durable performance each year. Height: 50cm (20"). 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.
