Growing Dahlias 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. Dahlia cultivars which flower the first year from seed are referred to as annuals. Many of these annuals form tuberous roots the first year. These tuberous roots can be saved for use next year. Perennial dahlias generally are purchased as tuberous roots.
