Dahlia is a genus of tuberous-rooted herbs in the family of Asteraceae, native to Central America and South America.
There are 42 species of this perennial plant and each of them come in different colors, sizes and shapes. Dahlia is considered as one of the most popular garden flowers because of its toothed green leaves and attractive colorful flowers.
It is unclear where the name actually originated. Many believe that Dahlia was named for the Swedish botanist Anders Dahl.
Dahlias generally represent beauty, elegance, grace, dignity and confidence.
They are widely known for their beauty and elegance that leave everyone amazed. Their beautiful shapes and vivid colors are just impossible to ignore.
These flowers bloom with grace and dignity, making them one of the most popular and easily recognized flowers on the planet.
Dahlias are not only beautiful, but they are also a pollinating paradise for bees and other pollinators. With their upright growth habit and magnificent blooms, they make striking vertical accents in borders and excellent cut flowers. They could therefore symbolize approaching life with a spirit that is confident and dynamic.

The Aztecs were very familiar with cultivating it. When Conquistadors conquered the Aztecs in the 16th century, they took various plants from the land back to Spain with them and one of the plants was the Tree Dahlia (Dahlia imperialis). They soon spread across Europe where they got their name. During the 19th century, the popularity of Dahlias rose and they became one of the most popular garden flowers in the world.
In 1963, President of Mexico, Adolfo López Mateos, decreed that the Dahlia should be the national flower of Mexico.
Dahlias come in just about every color, except blue.
In the 19th century, a London newspaper offered 1 pound to the breeder who would produce a blue Dahlia. Furthermore, the Caledonia Horticultural Society of Edinburgh offered a cash prize of 2000 pounds to whoever produced a blue Dahlia.
Up to today, all attempts to produce it have resulted only in several near blue cultivars, hence “blue dahlia” is used figuratively for something impossible or inaccessible.
Dahlia has been used as a medicine since ancient times.
Prior to the discovery of insulin, in America and Europe in the 20th century diabetics were often given a substance called “Atlantic starch” or diabetic sugar, derived from inulin obtained from Dahlia tubers. The Aztecs used the plant to treat epilepsy.
The plant is also used for dyeing.
However, Dahlias are mainly grown as ornamental plants in gardens. There are numerous cultivars that are highly ornamental in appearance and large in size, and growers constantly experiment with new varieties every year.
