Dahlias provide a riot of colour and months of flowering in public green spaces

Since the popularity of dahlias has skyrocketed in recent years, this has also led to their frequent use in public green spaces. This is due primarily to their extensive range of colours and how they continue to flower for months on end. It’s not only people who enjoy dahlias; bees and butterflies are also attracted to these flowers. Dahlias contribute to our quality of life and to the biodiversity of our cities.

Nectar and pollen

With such a long flowering period, dahlias enhance a location’s scenic value for months. Cities offer the perfect place for them in parks and roundabouts as well as in flower containers. The dahlia assortment is so huge that it includes almost every flower colour and many different flower shapes. Single and semi-double dahlias are so rich in nectar and pollen that they attract hordes of bees and butterflies. New assortments frequently become available on the market. Dark-leaved varieties are in high demand and make a beautiful addition to a planting.

Sturdy and not too tall

Dahlia varieties are classified into groups according to the shape of their flowers. The groups used in public green spaces need to be sturdy and not too tall. These locations often don’t provide the kind of support that the taller dahlias need. Among the suitable are:

Grouping together or combining with others

Dahlias make the most impressive displays when grouped together using just one or more varieties. For a more varied effect, dahlias could be combined with other summer-flowering bulbs such as Lilium (lilies), Canna (Canna Lily) and Crocosmia (formerly known as Montbretia). Dahlias can also be planted among perennials such as Pennisetum (Fountain Grass) or Persicaria (Knotweed). No matter what the variety, colourful dahlias will remind everyone that it’s summer - all summer long.
