Developed from blazing row naturally (5)
I believe the answer is:
grown
'developed' is the definition.
(thesaurus)
'from blazing row naturally' is the wordplay.
'from' indicates a hidden word.
'GROWN' is hidden in the letters of 'blazing row naturally'.
(Other definitions for grown that I've seen before include "Mature; raised" , "increased in stature?" , "Raised; having got bigger" , "Wrong (anag)" , "Increased; raised" .)
