Collection: Bachelor's Buttons | Cornflower Flower Seeds

Centaurea commonly known as Hardheads, Knapweed, Basket flower, Bachelor’s buttons, Bluebottle, Cornflower, Giant knapweed, Mountain bluet, are annuals, biennials, perennials and subshrubs found in dry sites, including woodland, rocky mountain slopes, subalpine meadows and sand dunes. They occur mainly in Europe and the Mediterranean with a few in Asia, Australia and North America. Centaurea are copious nectar producers especially on high lime soils. The high nectar yield makes it very attractive to insects such as butterflies including the endangered Karner blue which visits introduced spotted knapweed and day flying moths. Larvae of several true weevils also feed on the plants. This very high nectar production, coupled with its early blooming period, makes the plant helpful for the establishment of bee colonies in spring, a period that is often not well-served by commercial flower meadow seed mixes. Some perennials are grown as summer bedding annuals. Low maintenance
