In the garden
Dianthus plumarius originates from central and southern Europe and belongs to the Caryophyllaceae family. It produces clusters of fringed pink flowers with a distinctive clove fragrance through the main season, May to September, and typically makes short flowering stems to around 0.4 m. Position the plant in full sun on a sunny aspect. It tolerates a range of soils—sandy, loamy or clay—provided they drain; moist but well-drained conditions suit it best. Soil pH leans neutral to alkaline. Hardiness is H7, meaning it is fully hardy in UK gardens (USDA zones 4–9). Avoid waterlogging and give a free-draining, sunny site for the best flowering. Use Dianthus plumarius at the front of mixed borders, as an edging plant or in rock gardens where its compact habit and scented blooms can be close to paths and seating. Note the flowers are fragrant and the foliage is narrow; people who handle the plant should wear protective gloves because it can be a skin allergen. Mature plants normally stand at about 0.4 m tall.
