Decorative Dahlias have fabulous lush flowers ranging vastly in size from small to giant. They're dramatic and showy: a spectacular addition to the garden. They also make fabulous cut flowers for displaying around the home.  

There are 15 classes of dahlias, with the decorative dahlia perhaps being the largest and most popular class. Decorative dahlia flowers are our biggest range of dahlias for sale, with nearly 200 bulbs in our range, so you can be sure to find the right bulb for bulb for your garden.

What is a decorative dahlia?

Decorative dahlias grow between 50 and 90cm tall. Their double ray florets work outwards from the centre to hide the central disk and are available in a remarkable array of colours. Although a full flower is packed with petals, they still have the strength in the stem to stand upright. Decorative dahlias are also a fine flower for cutting and it is recommended to do so. The benefit of cutting dahlias is that it encourages new flowers to grow.

Stephen says

‘Decorative dahlias are always in my garden. There’s always new varieties for me to photograph for the website so I never stick to a theme. With so many colours on offer I have to accept each cultivar for their own unique beauty.’
