Dahlias are breathtaking flowers. Flowering for months, they inject color and drama wherever you grow them: in mixed borders in the garden, containers or window boxes on balconies and patios.
They are available in a rich variety of bloom colors, shapes, and sizes. Flowers can be as small as 2 inches in diameter or up to one foot. They can be single-flowering (orchid-flowering, anemone, and collarettes) or double-flowering (cactus, semi-cactus, formal or informal decorative dahlias, balls, and pompons). Their wide height range can start as low as 12 inches and go up to 6 feet.
Easy to grow, Dahlias thrive in full sun, well-drained sandy soils, although they can grow nicely in heavy clay soils – but adding some sand or peat moss would be a good idea.
There are thousands of varieties of dahlias (!!!), and many dahlia varieties can be fabulously gorgeous. Here is the list of our favorite dahlias.
