Shrub producing berries, strangely unripe after first of July (7)
I believe the answer is:
juniper
'shrub producing berries' is the definition.
(type of shrub that produces berries)
'strangely unripe after first of july' is the wordplay.
'strangely' indicates anagramming the letters.
'after' says to put letters next to each other.
'first of july' becomes 'j' (1st letter of 'july').
'unripe' with letters rearranged gives 'uniper'.
'uniper' put after 'j' is 'JUNIPER'.
(Other definitions for juniper that I've seen before include "Shrub flavouring gin" , "Shrub providing flavour for gin" , "Shrub with berries used to flavour gin" , "kind of berries" , "Coniferous shrub with berries used to make gin" .)
