About this seed

Why gardeners choose this variety

Blue Cornflower (Centaurea cyanus) is closely associated with European arable fields and the traditional cottage garden. Its vivid blue flower heads are made up of many finely cut florets, giving each bloom a soft, fringed outline.

Narrow grey-green leaves line slender, branching stems, keeping the plant light enough to mingle with other annuals. Grow in a sunny, well-drained border or a cutting patch, where the blue flowers add a clear accent among white, pink and yellow companions. Freshly cut stems bring the same airy character to informal bouquets.
