Dahlia

Dahlia are bushy, tuberous, herbaceous perennial plants in the Asteraceae family related to sunflowers, daisies, chrysanthemums, and zinnias. They come in nearly every color (except blue) in a huge variety of shapes and sizes. You'll find them in small pompons and singles to massive flowers up to 12+ inches across. They bloom midsummer through fall (until frost) and are popular as cut flowers and garden ornamentals. They are not frost-hardy, however, so if you live in a colder climate you'll want to dig them up and store them over winter.
