Black dahlia flower? We have them!

The search for a black dahlia often leads to the darkest shades found in the plant world. It is important to know that botanically, pure black pigments do not exist. The varieties referred to as black dahlias have a very high concentration of anthocyanins. This results in colors such as very dark wine red or deep purple. At Dahliastore, we have selected these special tubers directly from the Bollenstreek for you.

Care of the black dahlia

Dark varieties have similar requirements to other dahlias but need attention in specific areas. They prefer a sunny location, and the soil should be nutrient-rich and well-drained. A key factor for very dark flowers is solar radiation. Because dark surfaces absorb more heat, the petals can dry out faster during extreme heat. A location that offers light shade during the hottest hours of the day helps to preserve the dark color for longer.

Flowering time and cutting the black dahlia

Flowering usually begins in July and continues until the first night frost. To keep the plant healthy, it is advisable to remove spent flowers regularly. If you want to cut the dahlias for a vase, it is best to do so early in the morning when the stems are still full of moisture. The dark shades combine well in floral arrangements with light contrasting colors or warm autumn tones to emphasize the depth of the color.
