Roses may produce afflictions (5)
I believe the answer is:
'afflictions' is the definition.
(I've seen this in another clue)
'roses may produce' is the wordplay.
'may produce' indicates an anagram (I've seen 'might produce' mean this (I've seen this in other clues)).
'roses' with letters rearranged gives 'SORES'.
(Other definitions for sores that I've seen before include "Diseased spots" , "Lesions" , "Skin infections" , "Painful spots on roses" .)
