The Dahlia, scientifically known as Dahlia spp., is a genus of flowering plants native to the highlands of Mexico and Central America. Named after the Swedish botanist Anders Dahl, these vibrant blooms have a rich history dating back to the Aztec empire, where they were cultivated both for their aesthetic beauty and their edible tubers. Introduced to Europe in the late 18th century, Dahlias quickly gained popularity among horticulturists for their diverse range of colors, shapes, and sizes. Today, Dahlias are cherished worldwide as beloved garden flowers, prized for their stunning array of forms, from delicate single-petaled blooms to extravagant dinner-plate varieties.
