Dahlias

Dahlia ‘Café au Lait Rose’ is a breathtaking dinnerplate variety that offers a vibrant twist on the classic favourite, featuring massive, ruffled blooms in luscious shades of deep pink and magenta. A sport of the world-famous original, it retains the same impressive size and form but brings a richer, more intense colour palette to summer borders and bouquets.

Growing to a substantial height, this variety produces strong, sturdy stems capable of holding its heavy, multi-layered flowers. The petals curl and twist in a relaxed, informal habit, creating a sense of movement and luxury that makes it a standout feature in any garden scheme.

Plant in full sun to ensure the most vibrant colour saturation, in fertile, moist but well-drained soil. As a dinnerplate variety, it requires a sheltered spot away from strong winds to protect its large, heavy heads.

Water generously during dry spells to support the massive blooms, and deadhead regularly to encourage a continuous display until the first frosts. In colder climates, lift the tubers after the foliage blackens and store them frost-free over winter.

A brilliant choice for exhibition growing and luxury floristry, ‘Café au Lait Rose’ pairs beautifully with lighter pinks and creams, offering a romantic and opulent focal point at the back of the border.
