Cornflowers are native to Europe, including the UK, where it historically grew as a common wildflower in agricultural cornfields (hence the name "cornflower"

It is classified as fully hardy (H6) in the UK, capable of surviving temperatures down to -15°C to -20°C

While adult plants naturally die back after setting seed in late summer, autumn-sown seedlings overwinter perfectly as low-growing rosettes. They endure frost and snow to burst into rapid growth and early blooms the following spring

They tolerate poor soils, and act as a magnet for pollinators. Their sturdy stems and long vase life make them an excellent, high-yielding cut flower.

Culturally, they are used as edible flowers to garnish salads and cakes, or dried to add colour to tea blends (like Lady Grey). Extracts are sometimes used in cosmetics for their soothing properties, and historically, they produced a brilliant blue textile dye.
