Black Ball CornflowerCentaurea Cyanus, also known as the Black Ball Cornflower, is a hardy annual double flowered plant that grows easily from seed. Black Ball Cornflowers have a rich maroon or almost deep chocolate color that makes them appear almost black in certain lighting conditions. The dark blooms have a roundish appearance that resembles a pincushion and the green leaves are long and lance shaped. Multiple stems on the plant will provide many colorful blooms starting in early summer and continuing until the first frost appears in the fall. Some people describe the blooms of these plants as looking similar to a burst of fireworks. These flowers can add a touch of drama to any garden in which they are planted, due to their dark color and tall height of around 30 inches.

When and How to Plant

Centaurea Cyanus seeds can be sown directly outdoors during the months of March and April for summer blooming during the months of June, July, and August. These flowers prefer a very sunny spot in the garden and will thrive in areas with well drained soil. Seeds should be planted 1/8 of an inch deep and watered regularly until the plants are well established. Germination will typically occur within two to three weeks after sowing the seeds. After seedlings sprout, they should be thinned out so they are spaced around 6 inches apart from each other to avoid overcrowding. Deadheading the cornflower plants after the blooms have faded will encourage a longer blooming season and more blooms. Take care not to use too much fertilizer or you may end with more leaves than blooms on these plants.
