Cornflower / Centuarea

Cornflower Description

The cornflower or knapweed is a very popular and old hardy annual flowering plant. It is a florist's favourite and is frequently found in flower arrangements. Sprays of white, pink, blue, purple and red blossoms sit atop spindly narrow stems. The foliage is silver-grey.

Cornflowers display well in a garden bed on their own or as part of a cottage garden mix including marigolds and tall poppies.

In the past young me in love wore cornflowers and if the bloom faded quickly it was a sign that the love was unrequited.
