Beloved by bees and pollinators, beautiful, informal and just perfect for a cottage garden. Cornflowers make a brilliant-cut flower as they last so well in a vase and look wonderful amongst other blooms.

This variety is a soft lavender colour, an incredibly delicate and pretty flower yet robust, easy to grow and a great self-seeder.  Keep cutting and the flowers will keep on coming.

Seed Quantity 400 Seeds

Type Annual

Genus Centaurea cyanus

Sow Seeds Sow in September for larger, stronger plants and/or in late April.  Can be sown in modules to transplant later or direct into the soil.  Pre-water the soil before sowing.  Sow thinly and cover only very lightly. Do not let the soil dry out.  Grow in poor, well-drained soil and in full sun and it is advisable to grow through some netting as they are prone to flopping over in high winds without support.

Plant Out July- October.  Keep cutting and deadheading to encourage more blooms
