Part of flower, extremely sweet, with new name (6)
I believe the answer is:
stamen
'part of flower' is the definition.
(I know that stamen is part of bloom)
'extremely sweet with new name' is the wordplay.
'extremely' means to remove the middle letters (only the extremes of the word are used).
'with' means one lot of letters go next to another.
'new' is an anagram indicator.
'sweet' with its centre taken out is 'st'.
'name' with letters rearranged gives 'amen'.
'st'+'amen'='STAMEN'
(Other definitions for stamen that I've seen before include "Male ditto" , "Section of a flower" , "Part of a flowering plant" , "Male organ of plant" , "The pollen-bearing organ of flowering plants" .)
