Learn about the dark flower color, seed planting, and growing conditions of Black Ball Cornflower.
Black Ball Cornflowers are generally known for their very dark burgundy to deep maroon flowers, which can appear almost black in certain lighting. The exact shade may vary with growing conditions and individual plants. They are valued for their dramatic contrast with lighter flowers in ornamental garden displays.
In many temperate regions, cornflower seeds can be sown directly outdoors in spring after the soil becomes workable, or in fall where the climate allows suitable establishment. Planting time depends on local weather and growing zone. Follow the supplier's instructions for the best results in your location.
Grow the plants in full sun with well-drained soil and enough spacing for good airflow. Water during dry periods and harvest stems when the flowers are opening for floral arrangements. For a longer supply of blooms, consider successive sowings when local growing conditions are suitable.
