Petal pusher? (7)
I believe the answer is:
florist
'petal pusher?' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for florist that I've seen before include "One who deals in bouquets" , "Seller of blooms" , "Flower retailer" , "shop" , "A seller of flowers" .)
