"The Dutch information office of nutrition published a recipe for soup made of Dahlia tubers in the winter of 1944-1945: 1 1/4 litres of water, 1 kilogram of Dahlia tubers, 1/2 kilogram onions, salt, and a surrogate for pepper. The Dahlia tubers were to be washed and then rasped or the be cut in small pieces. The onions were to be cut in similar small pieces and to be baked alongside the Dahlia tubers in a little bit of oil. After adding the water and the salt, the whole thing had to cook for 30 to 45 minutes. It had to be finished off with a little of the pepper surrogate. That tulip bulbs were eaten in the Netherlands during the Second World War is common knowledge, but that the same thing was true for Dahlias has been long forgotten. That is mostly because tulips were much wider available and have therefore saved more lives; still, Dahlia's deserve a bit of the credit, too. We were however not the first to eat Dahlia's: the Aztecs who used to live in the land that is now Mexico, where the Dahlia originates from, used to eat Dahlia tubers as well. Oh, right, something about Penhill Dark Monarch in particular: like her sister Penhill Dark Watermelon, she is a Dahlia with cheerful flowers. They go well together, so combining them in your garden might be a recommendation."

Planting and caring for dahlia tubers

Plant dahlia tubers in spring once the risk of frost has passed and the soil has warmed. Choose a sunny position with nutrient-rich, well-drained soil. Place the tubers with the old stem or growing point facing upwards and cover them with approximately 5 cm of soil. Depending on the mature height of the variety, leave around 30 to 50 cm between the tubers.

Plant dahlias in a generously sized container with good drainage. They need regular watering during warm summer weather, but the tubers should not remain in wet soil for prolonged periods.

Read our complete guide to when and how to plant and care for dahlia tubers.

Our Dahlia tubers become available towards the end of the year for the following summer season. You can order them in advance, and we begin shipping from early March so they arrive in time for spring planting.

Dahlias are planted in spring after the last night frost, once the soil has warmed sufficiently. We recommend waiting until the soil temperature is around 15°C before planting.

Yes. Dahlias grow very well in pots. Choose a generously sized container, as Dahlias need plenty of water during warm summer weather and larger pots dry out less quickly.

Dahlias prefer a sunny position and well-drained soil. Large-flowered Dahlias in particular benefit from plenty of light and warmth, which helps them produce more flowers and bloom for longer.

Yes. Dahlia tubers can be started in pots indoors from March in a bright position. Once the risk of night frost has passed, the plants can be moved outside and planted in the garden.

For several Dahlia varieties, we recommend regularly removing faded flowers and seed heads. This encourages the plant to continue producing new flowers throughout the season.
