Grower (8)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
producer
'grower' is the definition.
(thesaurus)
This is all the clue.
(Other definitions for producer that I've seen before include "He works on programme" , "Manufacturer; film overseer" , "Zeffirelli perhaps" , "One creating" , "Procured (anag.)" .)
