Our selection of Centaurea with blue flowers. The blue colour is not rare in Centaurea - it can be found on the blooms of the Mountain Cornflower, a perennial, or those of the cornflower (Centaurea cyanus), a field annual. In this category we present perennial, biennial or annual species and varieties that offer flowerheads in different shades of blue to mauve. Centaurea montana has produced several beautiful cultivars with blue flowers, including "Coerulea". The cornflower, available as seeds, offers a great number of varieties ranging from light to the darkest blue, including variegated colours. The 'Classic Fantastic' selection perfectly illustrates this beautiful range of blue shades.
A wild and hardy field flower, the cornflower is honey-producing, edible, medicinal and ornamental. Robust and highly adaptable, this plant is easy to grow in any well-drained soil, including alkaline.
