The Dark and Dramatic CornflowerCornflower Blackball (Centaurea cyanus 'Blackball') is a stunning and unusual annual cornflower bearing large, fully double blooms in the deepest, richest burgundy-black — a dramatic and sophisticated colour that is almost unmatched in the annual garden. Far removed from the classic blue cornflower, Blackball brings a moody, velvety depth to borders and bouquets alike, and is an absolute showstopper when cut and arranged with softer pastels or bold brights. A must-have for the cutting garden and any gardener who loves something a little out of the ordinary.Why Gardeners Love It ⚫ Large, fully double deep burgundy-black blooms — a rare and dramatic colour that commands attention in any planting or arrangement ✂️ Exceptional cut flower — long stems and good vase life, stunning paired with whites, pinks, or bold colours 📏 Grows 70–90 cm tall — ideal for cutting gardens, cottage borders, and mixed beds 🐝 Attracts bees and butterflies — a valuable nectar source through spring and summer 🌱 Easy to grow from seed — direct sow and largely self-sufficient once established Growing Tips for New ZealandCornflowers are best direct sown into their final position as they dislike transplanting. Sow in autumn for spring flowering, or in early spring for summer blooms. Sow seeds 1 cm deep in a sunny, well-drained position and thin to 30 cm apart. Cornflowers are wonderfully unfussy — they thrive in average to poor soils and need little feeding. Deadhead regularly to extend flowering.
