Near-Black Blooms for Dramatic Contrast – An Unusual Summer Flower for Wildlife Gardens and Cutting

The Cornflower 'Black Ball' (Centaurea cyanus) is a particularly striking cultivar of the classic field flower, notable for its deep, almost black flower heads. While the wild cornflower once flourished across European grain fields, it has been increasingly displaced by industrial agriculture. Varieties like 'Black Ball' bring the wild charm back into our gardens – in a rare and dramatic colour variation.

The edible flowers of this variety are ideal for decorative use in salads, desserts, or as a topping for baked goods. Their almost black-red colour makes them a distinctive highlight on the plate. Unlike the classic blue cornflower, it is not significant as a dye plant, but stands out as an extravagant cut flower with strong visual impact in naturalistic or formal floral arrangements.

Cornflowers have a long cultural history as symbolic plants, wildflowers, and insect forage. 'Black Ball' is also bee-friendly, offering a valuable nectar source thanks to its extended flowering period.
