Blue cornflowers are simply majestic as well as edible. The unusual colouring has them standing out from the crowd and bursting with pollen for our native insects.

Each ball contains around 8 seeds, with around 20 balls per container - enough to cover 1 square metre or 3 large pots.

Best scattered in Spring or Autumn and watered as required, especially if there's a run of dry days during the growing season. Image with kind thanks to Maja Erwinsdotter
