P.S. In case the story did interest you in any way, and you are thinking that this is a bad ending, here is an alternative one:
They were all shocked by the death of the magical flower and they decided to hold a funeral next morning. The time was set and they agreed to have it in the same garden where they are all gathered anyway and since it wouldn't be logistically possible to hold it elsewhere, so that was not a problem. Next morning, everyone wakes up only to find they have all turned black.
You still don't like it? How about:
Next morning they all wake up ready for the funeral. Suddenly, two little boys arrive and were startled by the scene of hundreds of well aligned yellow flowers and they decided to surprise their mother with a big bouquet.
Okay enough: where is the rain? this is affecting my mental abilities.
