the Bachelore Button Flower
I planted the flower from seed, but the plant did not produce any flowers. Will it come back next spring?

There is a chance that there are still viable seeds laying around, but if it did not flower then it may not have seeded. If this is the case you will have to re-seed. Start them indoors earlier to ensure they reach full maturity.

If your bachelor button, aka cornflower, plants don't bloom, something is wrong unless you planted them late in the summer. They are annuals, vigorous bloomers and set so much seed that they are considered weedy. Too much fertilizer results in lush green growth and no flowers. Full sun, at least 6 hours, is necessary and plants don't tolerate wet soil. Did you notice any buds forming but not opening? There are several insects that destroy buds.
