Some species are: Centaurea cyanus, Centaurea cineraria, Centaurea cachinalensis, Centaurea moschata, Centaurea candidissima, Centaurea babylonica, Centaurea macrocephala. Common names: Bachelor's button, Cornflower. This species is native to Europe. They are annual herbaceous plants that reach 50 cm (1.64 feet) in height. They have thin, pointed leaves. The attractive flowers can be blue, pink or white. They bloom in summer and sometimes in late spring or early fall. They are used for curbs, mixed borders or groups in gardens, for cut flowers and in pots for balconies and terraces. Centaurea cyanus needs full sun exposure. They resist light and occasional frosts. The soil must be fertile, soft and permeable. Transplantation or planting is done at the end of flowering or in spring. Water with a glass of water per plant every 2-3 days in spring and summer; the rest of the year reduce the risks. They are resistant plants to the usual pests and diseases. They reproduce by division after flowering or from seeds sown in spring. |
