Flowering profusely until frost

Dahlias are spectacular summer flowers with an unprecedented variety of flower shapes, colours and heights. These tuberous plants are known for their profuse flowering from summer until late autumn. From compact pot varieties to impressive cut flowers over a metre tall – dahlias offer endless possibilities in gardening and cultivation. They are a favourite with both amateur gardeners and professional growers for their long flowering period, diversity and appeal to pollinators. Regular deadheading will keep dahlias flowering for months. Perfect for borders, flower arrangements and commercial cut flower production.

Dahlia – colourful star of summer and autumn

Dahlias are among the most beloved and versatile summer flowers. They owe their popularity to the enormous variety of flower shapes – from pompom and cactus to decorative and single-flowered – and to the fact that they can bloom continuously for months if properly cared for. The flowers are available in almost all colours except blue and can reach a diameter of up to 30 cm in the larger varieties.

Originally from Mexico, dahlias love warm temperatures and well-drained soil. They are planted in spring, as soon as the risk of frost has passed, and flower from July until the first frost. Dahlias can be grown in the ground or in pots, and are very suitable for cut flowers because of their sturdy stems and rich colours.

Application:

  • Borders and flower beds with rich, long-lasting flowering

  • Large pots and flower boxes for the patio or entrance

  • Cut flower cultivation (field or greenhouse)

  • Combination with ornamental grasses and perennials

  • Popular in flower arrangements and cutting gardens
