COMMON NAME: Dahlia
Dahlia is the grand, showy flower of the late summer, and it has been bred into a dazzling range of the forms, the colours and the sizes since it was brought from the highlands of Mexico. The heads range from the small, neat pompons to the huge, dinner-plate flowers, and the colours run through every shade but the true blue. The plants grow from the tuberous roots into bold, leafy clumps that flower from the middle of the summer to the first hard frost. It is one of the great flowers of the cutting garden and the show bench.
Scientific Research & Plant Biotechnology
The dahlia has a rich story in the plant science. It came to Europe from the highlands of Mexico as a food plant, and the tubers were studied as a possible crop before the flower took over, so the early botanical records are full of it. Researchers have studied the genetics of the flower forms and the colours, which has given the breeders the remarkable range we see today, and the plant keeps turning up in the work on the ornamental plant breeding. The high sugar content of the tuber has also drawn a quiet line of research, so the science here is deep and well recorded.
Ecological & Economic Value & Wide Applications
The dahlia is a serious cut flower, and a row of it in the garden keeps the vases full through the autumn. The single-flowered forms are a fine food source for the bees and the butterflies, and the tall, colourful heads make it a mainstay of the show garden and the bedding. The tubers have a long traditional use as a food in their homeland, and the modern varieties are grown all around the temperate world. It has drawn attention in the international horticultural press for its variety and its late, generous flowering, and it asks for the sun and the good soil.
The dahlia was a plant of the highlands of the Mexico long before the Europeans saw it, and the Aztecs grew it for its starchy, sweet tubers as well as for its flowers. The first plants reached the Europe as a food crop, and it was only later that the gardeners took it up and bred the astonishing range of the forms and the colours that we see today. In the Mexico it is the national flower, and the single-flowered forms are a fine food source for the bees and the butterflies. The long, strong stems and the huge, many-petalled heads make it a mainstay of the cut-flower trade and the show bench.
Dahlias are easiest from the tubers, but the seed is fun too. Sow the flat, papery seeds at a shallow depth in pots of moist, free-draining soil in the warm season, keep them in a bright, warm spot and water gently. The seedlings come up within a couple of weeks, and by the autumn each one will have formed a small tuber of its own. The first flowers are a surprise, since each seedling is a new variety, and that is half the pleasure of growing them this way.
