Black cornflowers
£2.50
Centaurea cyanus ‘Black button’
A classic for a reason. Easy to grow, tall, elegant, dramatic. Just tuck a few plants in odd corners, and you’ll always have some to hand. Remember to stake to get the best stem length out of them though, they do tend to fall.

Growing guide: Cornflowers are simple to grow and, as hardy annuals, they start quickly and easily from seed in either autumn or spring. I sow mine into 9cm pots (fill with a peat-free multi-purpose compost) in September and keep in a sheltered place over the winter. When I plant out into the ground at the end of April (they won’t mind a bit of frost), they will grow away wonderfully.
