Bush or Moss (4)
I believe the answer is:
kate
'bush or moss' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for kate that I've seen before include "'Kiss me, ---' (Shrew)" , "Katherine (dim.)" , "'Kiss me ___' (show)" , "Cole Porter musical 'Kiss Me ....'" .)
