Johnsons Wildflower Cornflower Seeds are sown for growing wildflowers in gardens. Because of their dashing blue colour, these flowers are often called ‘Bluebottle’). The flower has long stems, which once used to be a common sight in cornfields. Grown in the border or a wild garden, these flowers attract beneficial insects. These are native-grown wildflower seeds, not taken from the wild. A hardy annual. Sow from March into May or August to October to enjoy beautiful displays from June to September. The average pack contains 150 seeds. Height: 60cm.
