Native to damp meadows in the European mountain ranges, this perennial Centaurea is commonly called Mountain Bluet or Mountain Cornflower, and it is rugged and hardy, growing in most soil types and climates. The vigorous clump-forming plant has silvery-green foliage and stems that are slightly hairy. The blooms are large, solitary, and fringed and are excellent for cutting.

Mountain Centaurea is known for self-sowing, so deadheading is needed if spreading is not desired.
