Dahlias (Dahlia variabilis) are spectacular tuberous plants with large flowers in a great variety of shapes and colours. They flower from summer until the first frost and are among the most prized garden flowers for bouquets. The plant prefers sun and fertile, well-drained soils, and needs support for its tall stems.
