Cornflower (Centaurea Cyanus Tall Double Ball Black) - Easy-to-grow from seeds, this tall annual makes a great addition to the summer border. The color is a deep, rich claret which is as close to black as possible. Centaurea Cyanus Black Ball certainly adds drama! Cornflowers are especially nice in traditional cottage gardens, and they make an excellent cut flower. Also known as Bachelor's Button Black Ball, these flowers are native to much of the United States.
Bachelor's Button plants prefer full sun in mild climates and partial shade in the hottest regions. They tolerate a wide variety of soils as long as it drains well. Centaurea Cyanus performs the best in mild climates with moderate water, but the plants can tolerate drought. Cornflowers are very attractive to both bees and butterflies, but fortunately deer leave the plants alone.
Directly sow seeds outdoors in early spring as soon as soil can be worked. Prepare seedbed by loosening soil and weeding. Sow the flower seed in rows ensuring you sow at least 6 seeds per foot. Thin young plants to 6 - 12 inches apart. In mild winter climates, seed can be sown in the fall for very early blooms the following spring. Cornflowers will drop their mature seeds and often self-sow providing climate conditions work out.
