End around middle of July for flower (5)
I believe the answer is:
tulip
'flower' is the definition.
(thesaurus)
'end around middle of july' is the wordplay.
'end' becomes 'tip' (tip is a kind of end).
'around' means one lot of letters goes inside another.
'middle of' indicates the central letters.
The middle letters of 'july' are 'ul'.
'tip' going around 'ul' is 'TULIP'.
'for' acts as a link.
(Other definitions for tulip that I've seen before include "Flowering bulb (from Amsterdam?)" , ""Dutch" flower" , "Dutch export" , "Amsterdam bloom?" , "Plant of the lily family with a single showy flower" .)
