Sow Bachelor Buttons seed directly outdoors, in spring, when the danger of frost has passed. Prepare the seedbed by loosening soil and weeding. Sow the cornflower seed in rows, 6 seeds per foot. Thin small seedlings to 6 - 12 inches apart. In US southern states with mild winter, sow the seed in the fall for early blooms the following spring. The first blooms show up 10 - 12 weeks after planting, and last for about a month. Successive plantings can extend the blooming period.

Every seed I planted germinated and grew. Still not to flowering stage but they all continue to grow nicely.
I followed the instructions & it seems like all the seeds germinated.
I would say 90% of the seeds were germinated indoor within a week and the seedlings are strong. I can’t wait to see them grow and bloom after the weather is warm.
