Flower cluster (6)
I believe the answer is:
raceme
'flower cluster' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for raceme that I've seen before include "Flowers evenly spaced along central stem" , "Elongated cluster of flowers along a main stem" , "something flowery" , "Long cluster of flowers on one stem" , "flower arrangement" .)
