Centaurea montana, commonly known as Cornflower, is a first year flowering perennial wildflower. The striking beauty of the violet-blue flowers is as captivating as its textural interest. Fringed petals emerge from its decorative "basket weave" bud base nestled in bright purple quills. Stunning! Heralding from the damp meadows in the European mountain ranges, it is most prolific in moisture retentive soils but has adapted well to most climates and soil types. Deadhead spent blossoms to prompt continual blooms from early summer through fall. 24" inch plants freely self sow, so act accordingly, removing all expired blooms if you do not want a swath to naturalize. Centaurea montana is easy to grow from seed and a sought after cut flower variety by floral creatives. Hardy to zone 4. Packet: 25 seeds.
