Dahlias are stunning summer-blooming tubers native to Mexico, known for their incredible diversity in size, shape, and color—from tiny pompons to massive dinnerplate blooms. They're a favorite for cut flowers because they produce abundantly from midsummer until frost and make jaw-dropping bouquets.

In most climates, dahlias start blooming in mid-to-late summer (July-August) and continue nonstop until the first hard frost in fall.

Dahlias are tender perennials. In zones 8-10, they can overwinter in the ground. In colder zones (like 7 and below), you'll need to dig and store the tubers over winter.
