Pink dahlia flower  July 23, 2026

Some flowers quietly fill a garden. Dahlias arrive as if they have been cast in the lead role. Native to Mexico, these members of the daisy family come in more than 57,000 cultivated varieties, thanks in part to their unusual genetics. Dahlias are octoploids, meaning they have eight sets of chromosomes, which helps create blooms that range from tiny buttons to 36 centimetres across.
