Giant Dinnerplate Dahlia Grand Prix

Giant Dinnerplate Dahlia Grand Prix

Huge, fully double, bright yellow flowers are tipped with white for a truly radiant and cheerful look. Grand Prix Giant Dinnerplate Dahlia is the ultimate showstopper in the garden.

While impressive in the garden, they're also impressive in cut-floral arrangements. Best of all, Grand Prix Dahlias take little to no special effort to grow, yet will flower all season long until the first frost.
