Garden Dahlia is a tender perennial prized for its spectacular, long-lasting flowers in a wide range of colors and forms. It blooms prolifically from summer through fall and requires staking for taller varieties.
Why grow it
Dahlias offer an extended bloom window and exceptional color range compared to many summer perennials, making them valuable for late-season garden interest. They produce substantial cut flowers reliably across a range of forms, from simple singles to elaborate doubles, which distinguishes them from single-form alternatives like zinnias or cosmos. Their ability to flower prolifically into fall gives them practical advantages in regions with shorter growing seasons.
Watch out for
Dahlias require consistent deadheading to maintain bloom production, and neglecting this can result in premature flowering decline. While taller varieties benefit from staking, the practice demands attention to prevent stem damage as plants mature and flower weight increases. Tuber storage over winter in cold climates requires cool, dry conditions, and poor storage conditions can lead to rot or sprouting before planting season.
