Propagation, culture, diseases, and insects of dahlias are covered here.

The dahlia is a versatile flowering plant, providing a wide array of sizes, forms and colors. Flowers range from half-inch pompons to giants. Flower forms vary from daisy-shaped singles to fully double types with intermediate forms, such as anemone.
