The diversity of dahlias
Once the flowers produced by spring bulbs have faded away by around mid-May, space for dahlias becomes available for creating a real summer park. Often used for this purpose are pot dahlias produced in nurseries and made available as bedding material. Sometimes, however, dahlia tubers are planted among perennials. The range of dahlia varieties is huge and so is the variation in their flower colors, leaf colors and heights. And new cultivars are always being added. The ones with compact habits are perfect for planting in parks. Take the single-flowered Mignon Single Dahlia, for example, or the semi-double Anemone Dahlia.
A long flowering period
Dahlias supply the beautiful look of summer month after month: after all, they bloom from July until the first ground frost. They are available in solid colors of white, yellow, orange, red, and purple and there are also bicolored varieties. The large quantities of pollen and nectar produced by the single and semi-double flowers make them attractive for bees, bumblebees and butterflies. After flowering, they can again be replaced by spring-flowering bulbs. Meanwhile, small trees, shrubs or ornamental grasses add visual interest to the winter park – and then spring comes around again.
- Planting groups of dahlias provides the prettiest effect. There are many different combinations on the market, but a bed filled with the same variety also makes a delightful sight.
- Removing dried-out flowers encourages the production of more flowers with more intense colors.
- The unique look of dark-leaf dahlias is currently making them a popular choice.
- Dahlias are real sun-worshippers: sun all day long is no problem. They also thrive in flower containers.
- Mexico is the original habitat for dahlias, so, not surprisingly, they are treated as annuals since they won’t survive the winter.
