Corncockle with its straight stems, purplish-pink flowers and silvery-grey foliage used to be a common sight in the wheat fields and along the roadsides. It must have been an idyllic, heartwarming sight to see. This is a happy easy-to-grow cut flower and a favourite of ours. Grow it once and you’ll be hooked!

From mud spring and well into summer, Corncockle provides a rich profusion of flowers. The ability to rebloom is a long-lasting addition to your garden.
