purple lantana was fully bloomed then in a day all flowers died

Question

There are no other details; one day the plant was beautiful, the next all the flowers were dead. If this happened before I never noticed, which is unlikely.
The leaves are healthy.

Answer 1

This can happen with excessive heat, or dry weather. I would not worry too much, unless you are seeing other symptoms. It will likely bloom again once you trim the dead flowers.
