In the garden

Dianthus 'Thomas' is a perennial member of the Caryophyllaceae, cultivated for its scented blooms and summer display. As a Dianthus it shares the group's preference for sunny, open positions and soils that do not remain waterlogged. Expect flowering from May to September and a clear spicy scent while in bloom. Place Dianthus 'Thomas' where it receives full sun and is sheltered from prevailing winds — a south-facing spot suits it best. Provide a free-draining soil with neutral to alkaline reaction and avoid heavy, water-retentive ground; moderate soil moisture is sufficient rather than constant wetness. It carries an H5 rating, meaning it is hardy in most UK gardens with normal winter conditions. Use plants singly or in groups at the front of borders, tucked into rock gardens, or in pots where soil can be kept reliably free-draining. A sheltered position close to the house or on a sunny patio will concentrate the scent from its summer flowers, making it a practical choice where fragrance matters as much as appearance.
