They will flower all summer into late Autumn.

Dahlia are breathtakingly gorgeous flowers, that come in nearly every colour you could dream of. Dahlia are a genus of tuberous plants of the Asteraceae family. Pollinators like bees and butterflies, are drawn to dahlias, which provide a rich source of nutrition. Brought to Europe in 1789, named after the Swedish scientist Andreas Dahl.

Decorative Dahlias are exactly that, decorative. They all have double flowers. They have petals that are usually flat and wide. An excellent choice for cut flowers.

    Our pot & plant size explained

    At Newlands Nursery we grow and sell plants in a variety of different sizes, from small starter plants up to planted containers. 

    We know it can be tricky to picture the size of each plant. This page gives you an idea of the size of the plants we are sending out.

    Please keep in mind that plants vary from one season to the next. The size of the plant refers to the pot or plug it is grown in, rather than the height of the plant, unless specifically mentioned on the plant page.

    Starter Plant (Plug Plant)

    Plug Size: 2cm by 4cm. Our most popular size. This is often the most economical way of buying plants and is a great way to get a head start on the season. Generally this size is best to be potted up before planting out.
