I think it wouldn’t be dead until it looses all of its color and is able to crumple in your fingertips. So basically, it isn’t dead yet when it is wilted. But Its getting to the stage of being dead (like how old people are at that stage of their life where they will pass away soon).
To put it simply, the flower is not dead yet, it’s just “old” :D
