Why grow orange dahlias?

I always think that orange dahlias are offer a burst of colour that captures the essence of summer, especially when they catch the golden glow of evening sunlight.

The beauty of orange dahlia varieties lies not only in their individual effect but also in their ability to blend superbly with other hot-coloured dahlias. When paired with red dahlias, yellow dahlias, and pink dahlias, they create a truly sizzling border. The diverse shapes and sizes of orange dahlia varieties contribute to this mix, with many also attracting pollinators and beneficial insects.

Orange dahlias also offer a striking effect when juxtaposed with contrasting perennial plants. They can anchor a garden’s design with their bold presence and look especially effective when set against the deep purples, striking blues, or serene whites of perennial companion plants.
