The majority of foxglove varieties display blossoms in late spring to early summer. Once the petals fall off, the plant will generate seed pods with plenty of tiny seeds. When the foxglove’s seed pods are mature, they release the seeds.
You can expect the flowering season to begin in mid-summer and last until the first frost. To encourage your calendula to produce more golden blossoms, deadhead the spent flowers regularly.
At the end of the flowering season, honeywort blossoms will begin to produce seeds. If you want to save the seeds for the next season, wait until the pods turn brown and dry out.
This is an annual plant, which means it will die back after it generates flowers, but if you don’t remove all the flower heads, you can get an abundance of blossoms the following season. As the years go by, you can expect more and more blossoms.
