A bit of flower power -- and others (5)
I believe the answer is:
petal
'a bit of flower' is the definition.
(I've seen this before)
'power and others' is the wordplay.
'power' becomes 'p'.
'and others' becomes 'etal' (synonyms).
'p'+'etal'='PETAL'
(Other definitions for petal that I've seen before include "part taken from stock?" , "A bit of a bloomer" , "A bit of flower" , "Flowery term of endearment?" , "Colourful flower part" .)
