They're easy to grow, even for beginning gardeners, and they're a pollinator's dream come true - bees and butterflies love them. Cornflowers are versatile and can be used in wildflower meadows, cottage gardens, borders, and even containers.

To get started, you can sow cornflower seeds in the spring or autumn, and they'll self-seed if the ground is bare in the autumn. If you're sowing in the spring, you can broadcast the seed and then roll the ground afterwards. If you're sowing in the autumn, you can mix them with other annuals, such as poppies, or sow them on their own.

Cornflowers need support as they grow, so make sure to insert 1m hazel sticks around the planted area and lower two layers of mesh netting over them. This will help them stand straight and look their best. And, just like sweet peas, cornflowers need to be cut constantly if you want them to flower all summer - cut them just before they open fully.

Here are some key things to keep in mind when growing cornflowers:
