Said to the fallen, but pulls out a flower (3-1-5)

'flower' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'said to the fallen but pulls out a' is the wordplay.
I cannot really see how this works, but
an anagram of 'said' is 'dais' which is located in the answer.
'a' is found in the answer.
The remaining letters 'upsy' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
