From tubers to flowers
The dahlias are blooming again! From pastel-coloured to brightly coloured and in thousands of shapes and sizes, but all equally beautiful and unique.
The dahlia originated in Mexico and is related to the sunflower, the daisy, the chrysanthemum and the zinnia. The dahlia is a tuberous plant and grows in almost any type of soil, but can also be kept in a pot. With a flowering period from mid-August until far into the autumn, the dahlia provides an explosion of colour in the fields and show gardens of the Bulb Region.
The exuberantly flowering dahlia not only has a great attraction to people but is also very popular with bees, bumblebees and butterflies!
