Cornflower
Centaurea cyanus
Cornflowers can be grown all year round, just avoid sowing seeds and transplanting through hot or cold weather.
They are a compact annual growing up to 50cm, with excellent cut flowers.
Cornflowers don’t require a lot attention, but cut old flowers off just above their leaves to extend their flowering season and encourage new flowers.
