Cornflower 'Blue Ball' seeds
Close your eyes and imagine a country cottage garden. Slightly wild and utterly charming, overflowing with colour, scent and the peaceful humming sound of busy pollinators. Which flowers come to mind? Possibly roses, perhaps hollyhocks?.... and most definitely cornflowers. No cottage garden would be complete without them.
Once a common sight in cornfields across the UK, before the use of herbicides, these brilliant, cobalt blue, native flowers are now a rare sight but thankfully live on in our gardens. They are a dream to grow. Easy, prolific, (producing endless amounts of flowers over several months if you keep on top of the dead-heading), beloved of butterflies and bees and will happily self seed.
They also make excellent cut flowers, lasting for 5-7 days in a vase.
Sow the seeds directly where they are to grow in mid April or mid September. The autumn sown seeds will produce taller plants and flower earlier. Cornflowers like a sunny, well drained spot. Rake the soil and make your drills 6mm deep ready to receive the seeds. Prewater the drills (to stop the seed being washed away) and sow thinly. Cover lightly with soil.
When the seedlings start to show, thin them to around 20cm apart and keep the soil fairly moist whilst they are growing.
Cornflowers are tall plants and will need support to keep them straight, so provide netting/mesh for them to grow through.
