Press round outside of ‘death' flower (7)
I believe the answer is:
blossom
'flower' is the definition.
(I know that flower can be written as blossom)
'press round outside of death' is the wordplay.
'press' becomes 'mob' (I've seen this before).
'round' says the letters should be written in reverse.
'outside of' indicates putting letters inside.
'death' becomes 'loss' (loss is a kind of death).
'mob' written backwards gives 'bom'.
'bom' placed around 'loss' is 'BLOSSOM'.
(Other definitions for blossom that I've seen before include "Do well" , "Produce flowers" , "Flowers on a tree/bush" , "Flowers on tree or bush" , "Flowers (on tree, shrub)" .)
