Cornflower 'Perennial Butterfly'

This summer-blooming perennial takes center stage in the world of important bee and butterfly plants. The vibrant violet thistle-like flowers are rich with nectar and pollen and adorn casual borders and meadow plantings with their fringed flowers. Native to Europe, where it is often called greater knapweed, it is a well-behaved member of the Centaurea genus. Lime-enriched soil suits it best.
