More Details

Centaurea cyanus ‘Blue Boy’ is a large-flowered cornflower in classic bright blue. This wonderfully coloured bloom will continue for 2-3 months in the summer.

This is one of the prettiest wild flowers, and it used to populate entire fields with its incredible hue. Its juice even used to be extracted and mixed with alum to make a watercolour.

No cottage garden is complete without cornflowers; loved by pollinators and brilliant as cut flowers. We use lots of them to make table runners and napkin rings for wedding and party flowers, as they last brilliantly out of water.
