Inferior part of flowers (5)
I believe the answer is:
lower
'inferior' is the definition.
(similar in meaning)
'part of flowers' is the wordplay.
'part of' indicates a hidden word.
'LOWER' is hidden within 'flowers'.
(Other definitions for lower that I've seen before include "Jersey perhaps" , "where are trousers in relation?" , "Let down; frown" , "Cow" , "Bring down" .)
