Filled with foliage (4)
I believe the answer is:
lush
'filled with foliage' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for lush that I've seen before include "Drunk" , "Growing luxuriantly, grass say" , "one mortal too often" , "Verdant" , "Habitual drinker (slang)" .)
