Cutting Italian flower, suggested removing head (7)
I believe the answer is:
pointed
'cutting' is the definition.
(thesaurus)
'italian flower suggested removing head' is the wordplay.
'italian flower' becomes 'Po' (Italian river - something which flows).
'suggested' becomes 'hinted' ('hint' can be a synonym of 'suggest').
'removing head' means to remove the first letter.
'hinted' with its first letter taken off is 'inted'.
'po'+'inted'='POINTED'
(Other definitions for pointed that I've seen before include "Aculeate" , "Of remark, direct and cutting" , "Sharp-ended" , "Direct and obvious in meaning" , "Sharply tapered" .)
