Vibrantly colored flowers with soft, quilled petals are sure to delight in the sunny garden. Colorful Decorative Dahlia Mix is a random mix of colors and may include white, yellow, red, pink, purple and other hues. Growing 24-36" tall, decorative dahlias produce more, but smaller blooms than their dinnerplate cousins. The mid-sized flowers are great for fresh-cut bouquets and arrangements. Like other dahlias, decorative dahlias bloom from midsummer to the first frost in the fall. Deer tend to pass them by.
