Centaurea cyanus is a cute and bright blue wildflower, also known as cornflowers or blue bottles, get their unique nickname from how they were used. Plant your bachelor's buttons seeds towards the tail end of winter for gorgeous blue blooms from early summer onwards. These flowers enjoy full sun and grow best in well-drained soil. The vibrant wildflower is pretty drought tolerant but does prefer to be watered fairly regularly.
