As a genus boasting thousands of cultivars, Dahlia flowers have become a symbol of elegance, resilience, and the boundless creativity of nature.
History and Origin of Dahlia Flowers
The history of the Dahlia dates back to the 16th century when Spanish explorers first encountered the flower in the gardens of the Aztecs. Revered by the indigenous people for its beauty and symbolic significance, the Dahlia soon found its way to Europe, where it underwent centuries of hybridization and cultivation. By the 19th century, Dahlias had become a popular ornamental plant, finding a place in the gardens of royalty and commoners alike.
