Interesting facts about Dahlia

Dahlias in the United States

In 1913, the city officials of Seattle declared the Dahlia to be its official flower. There is nowhere better to see them than the Volunteer Park Dahlia Garden where they are in full bloom during August.
Dahlia has also been the official flower of San Francisco since 1926. Dahlias at Golden Gate Park start to bloom in June and continue till September.

Dahlias in Mexico

Dahlia is the national flower of Mexico.
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.

The Mystery of Blue Dahlia

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.

Benefits and Uses

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.
