Pansy part (5)
I believe the answer is:
petal
'pansy part' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for petal that I've seen before include "Flower part seen on plate" , "Flowery term of endearment?" , "A bit of flower" , "A bit of a bloomer" , "part of seven [VIOLA]" .)
