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.
Premium perennials are large plug tray plants, roughly the same size as garden ready plants like a potted plant without a pot. They will need to be acclimatised to the garden, and once all chance of frost has cleared can be planted out directly into the garden.

Pot up Sweet William plug plants and grow them on in frost free conditions for transplanting into borders and containers later on. When all risk of frost has passed, and plugs are fully rooted into their pots, acclimatise them to outdoor conditions over 7 to 10 days. Plant Sweet Williams in beds and borders in fertile, well drained soil in full sun.

Thompson & Morgan strives to ensure that all its plants are delivered to you in the perfect condition for planting. While the majority of our nursery plants cope well with slight delays in intransit, sadly, the time it takes to deliver to certain locations in the UK means that we can't guarantee this for some of our smaller plug products and tender bedding and vegetable lines, which do not respond well to the extra journey time. So regretfully while we offer the majority of our live plant offering nationwide, we are unable to ship plugs, begging plants and tender vegetable plants to the following areas: HS, IV41-IV49, IV51, IV55-56, KW15-KW17, PA34, PA41-48, PA60-PA78, PA80, PH40-PH44, TR21-TR24, ZE1-ZE3
