Collection: Dahlia Plants

Dahlia plants are prized for showy flowers and an extraordinary range of colors, shapes, and sizes. Dahlia flowers may be neat and geometric, wildly ruffled, or somewhere deliciously in between. They thrive in full sun with rich, well-drained soil and regular water during active growth, producing abundant blooms from summer into fall; exact timing varies with climate.

Use dahlias in beds, borders, roomy containers, and cutting gardens, where their long-lasting blooms can move straight from garden scene-stealer to bouquet. Deadheading spent flowers helps keep many varieties blooming, and taller plants may appreciate support. Check each plant page for mature size, habit, and local growing guidance, then explore our collection of dahlias to find the right color and form for your garden.
