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 the answer is hidden within the clue.
'LOWER' can be found hidden inside 'flowers'.
(Other definitions for lower that I've seen before include "Jersey perhaps" , "where are trousers in relation?" , "Let down; frown" , "Cow" , "Bring down" .)
