When a flower grows in bad conditions it is unlikely to strive. The plant may wither and die, or develop diseases.
After flowers wither, the flower will become a fruit because of pollination.
If the flower has been pollinated a seed pod will develop.
Once the fruit of the flame of the forest flower starts to develop, the petals typically fall off. This process allows the flower to focus its energy on fruit production and seed development.
After fertilization, the petals of a flower wither because their purpose of attracting pollinators to facilitate reproduction has been fulfilled. The plant then redirects its energy towards developing seeds, so resources are no longer needed to maintain the petals.
The sole purpose of the flower is to attract a pollinator. Once the flower has done it's job it is superfluous so is discarded to save energy.
After fertilization, the ovary develops into a fruit while the flower petals wither away. The ovules inside the ovary develop into seeds, and the ovary wall matures into the fruit to protect and nourish the seeds as they develop.
During drought plants will wither (or dry out)
