Its fruits are possibly ripe after one short month (7)
I believe the answer is:
juniper
'its fruits' is the definition.
I can't judge whether this defines the answer.
'possibly ripe after one short month' is the wordplay.
'possibly' indicates anagramming the letters.
'after' is a charade indicator (letters next to each other).
'one short month' becomes 'jun' (I am not sure about this - if you are sure you should believe this answer much more).
'ripe' with letters rearranged gives 'iper'.
'iper' after 'jun' is 'JUNIPER'.
'are' is the link.
Can you help me to learn more?
(Other definitions for juniper that I've seen before include "Shrub providing flavour for gin" , "Evergreen shrub or small tree with berry-like cones" , "kind of berries" , "Its cones are used to flavour gin" , "Plant producing berries used to flavour gin" .)
