How the foliage goes (6)
I believe the answer is:
leaves
'foliage goes' is the definition.
'leaves' can be an answer for 'goes' (I've seen this before). I am not sure about the 'foliage' bit.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for leaves that I've seen before include "spinach for example" , "some tea, perhaps" , "they add to a bed, as > does a bunk" , "''... of Grass'' (Walt Whitman)" , "Abandons" .)
