Large ivory cornflowers bloom all summer above clumps of long grey-green foliage. These plants are very resilient in coastal areas, where they happily thrive in salty winds and drought but they’re just as at home in the cottage garden. Like its relative centaurea montana, these perennial cornflowers are very undemanding and give plenty in return.
