Rush ahead of me to find flower arrangement (6)
I believe the answer is:
raceme
'flower arrangement' is the definition.
(I've seen this before)
'rush ahead of me' is the wordplay.
'rush' becomes 'race' (synonyms).
'ahead of' is a charade indicator (letters next to each other) (some letters go in front of others).
'race'+'me'='RACEME'
'to find' is the link.
(Other definitions for raceme that I've seen before include "Long cluster of flowers along the main stem" , "something flowery" , "Flower cluster (botany)" , "Flowers evenly spaced along central stem" , "Elongated cluster of flowers along a main stem" .)
