General Information

The great variety results from dahlias being octoploids (they have eight sets of homologous chromosomes, whereas most plants have only two).

The Aztecs gathered and cultivated the dahlia for food, ceremony, as well as decorative purposes, and the long woody stem of one variety was used for small pipes.

The introduction of the dahlia to the florists of the Netherlands was effected around 1790, when a box of dahlia roots was sent from Mexico to the Netherlands. Only one plant survived the trip, but produced spectacular red flowers with pointed petals. Nurserymen in Europe crossbred from this plant, which was named Dahlia juarezii, with parents of dahlias discovered earlier and these are the progenitors of all modern dahlia hybrids.

VIDEO: All About Dahlias - How to Plant Dahlia Flowers from White Flower Farm
-----------------------------------------------------------------------------

Dahlias are members of the Daisy family and native to Central America. In the United States, they are hardy only in Zone 8 and warmer, so most gardeners must grow them as annuals. We start plants from tubers each year, and they grow quite quickly to reach peak bloom from August to September, a time when their colorful, diverse flowers put a fresh face on our display gardens. There are so many interesting flower forms and sizes that is it difficult to limit yourself once you start growing Dahlias.

In our video, youll see a number of forms head gardener Cheryl Karpeichik currently grows (decorative, informal decorative, dinner-plate, ball, cactus, anemone, and orchid) and learn about planting tubers, staking, and deadheading.
