With unique orb-shaped blooms that appear in a multitude of glorious colors, Giant Ball Dahlias should top your list of garden must-haves this spring. Flowers are very large—up to 5½" in diameter, giving mass plantings a distinctive polka dot effect. Giant Ball Dahlias bloom from July to October, ceasing only when the first fall frosts arrive on the scene. We love these amazing cultivars for their versatility and easy care nature. They are hardy in zones 3-10 and only need to be lifted in fall for a striking display that reappears year after year. Giant Ball Dahlias make exceptional cut flowers.
