Black Ball Cornflower Seeds

Sow Cornflower Black Ball seeds directly in the ground in early spring, as soon as soil can be worked. Don't start them indoors, as their taproot develops fast and transplanting sets the plant back for a few weeks. These are cold season flowers, and cool soil actually improves germination, which typically takes 7–14 days. In zones 7 and warmer, you can sow Black Ball Cornflower seeds in fall to get spring blooms. Cover seeds with about ¼ inch of soil and water regularly until sprouts appear. If you want flowers across most of the season, stagger two sowings in 3–4 weeks.

Cornflower Black Ball plants need full sun, at least 6 hours per day. Cornflowers can handle poor, dry soil, provided it is well drained.. A neutral pH around 6.0–7.0 is ideal, and there's no need to fertilize plants, as rich soil pushes leafy growth at the expense of flowers. Water consistently while the flower is getting established, then back off, as mature plants become drought-tolerant.

Thin seedlings to 9–12 inches apart when they're 2–3 inches tall to ensure good airflow. Stake tall stems if your planting area is exposed to wind. Deadhead regularly to extend flowering. For cutting, harvest in the morning when buds are just cracking open. For drying, cut before full bloom and hang upside down in a dark place with good airflow.
