A Bit of History

Lavender Perfection has been a staple in dahlia circles for decades — beloved by both home gardeners and professional growers for its combination of size, beauty, and reliability. It’s one of the most recognized giant-flowered dahlias, often winning hearts (and ribbons) at flower shows. Despite its enormous blooms, it’s surprisingly easy to grow, thriving in full sun with regular deadheading. This variety proves that perfection doesn’t have to be rare — just well loved.
