Dahlia

The dahlia is a beautiful flower from Mexico with historical roots stretching back centuries. Dahlias are well-known for their brightly colored flowers, which bloom continuously all year round.

Purple Dahlia

Dahlia (Dahlia pinnata) is Mexico’s national flower, officially declared so in 1963. Native to the country’s mountainous regions, dahlias boast an extraordinary range of forms, from simple, daisy-like blossoms to large, ornate, multi-petaled “dinner plate” varieties.

Colors span nearly every shade except true blue. In Aztec times, dahlias were grown for their edible tubers and used medicinally. The Spanish brought them to Europe in the 16th century, but Mexico remains the dahlia’s cultural heart. Traditional meanings tied to dahlias include inner strength and creativity, embodying the flower’s ability to thrive in rugged, volcanic soils.

Dahlia is available in various shapes, colors, and sizes, which makes it popular with florists and gardeners. Dahlias, along with sunflowers and daisies, belong to the Asteraceae family.
