Bloomer harms chutney prepared by mother initially (13)
I believe the answer is:
chrysanthemum
'bloomer' is the definition.
(chrysanthemum is a kind of flowering plant)
'harms chutney prepared by mother initially' is the wordplay.
'prepared' is an anagram indicator.
'by' means one lot of letters go next to another.
'initially' says to take the initial letters.
The first letter of 'mother' is 'm'.
'harms'+'chutney'='harmschutney'
'harmschutney' is an anagram of 'chrysanthemu'.
'chrysanthemu'+'m'='CHRYSANTHEMUM'
(Other definitions for chrysanthemum that I've seen before include "Ornamental flower" , "Common garden flower" , "National flower of Japan" , "Flower, literally golden one" , "Perennial" .)
