Wild British Cornflower, 5 g - 1000 Seeds - Covers 3 m²

Wild British cornflower seeds produce one of Britain’s most recognisable native annual wildflowers, with vivid blue, star-shaped flowers held above fine grey-green foliage. Once a familiar sight in arable fields, cornflowers now play an important role in restoring colour and insect life to gardens, wildlife margins, and meadow plantings.

These easy-to-grow seeds establish readily in most well-drained soils and reward even small patches of ground with weeks of bright summer flowers. Like many traditional arable wildflowers, Centaurea cyanus performs well in lighter, lower-fertility soils where competition from grasses is limited.

Cornflowers are particularly valuable for pollinators, attracting a steady flow of honey bees, bumblebees, solitary bees, and butterflies throughout the flowering period. Their open flower structure, along with extra floral nectaries on the foliage, provides additional nectar sources for beneficial insects, helping increase pollinator activity across the garden.

Seed coverage

A 5 g packet contains approximately 1000 cornflower seeds, enough to sow around 3 m² at a dense rate for a strong, colourful display. If scattered more thinly as part of a mixed wildflower area, the same packet can comfortably stretch to 6–10 m² depending on spacing and soil conditions. Many gardeners prefer a lighter sowing to create a natural meadow-style patch, allowing each plant space to develop sturdy stems and branching flowers.

Wild cornflower works well in wildflower meadows, pollinator strips, cottage-style vegetable gardens, and mixed annual wildflower areas. In productive gardens, the increased insect activity also helps support pollination of nearby crops. For the strongest displays, sow cornflower seeds in autumn or early spring, scattered onto lightly raked soil where they can establish naturally.

With a little space and the right conditions, cornflowers quickly bring colour, movement, and the gentle hum of pollinating insects back into the garden.

Sowing Instructions

• Scatter seeds onto a fine, weed-free seedbed and gently rake in.

• Keep the seedbed moist after sowing for successful germination.

• Protect young seedlings from slugs and snails.

• Remove weeds as seedlings grow to reduce competition.

• Autumn sowings may flower slightly earlier than spring sowings.

• After flowering, cut back dead vegetation and lightly cultivate to encourage natural reseeding.
