Vine-covered (5)
I believe the answer is:
ivied
'vine-covered' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ivied that I've seen before include "Clad in evergreen" , "Covered in Hedera helix" , "with covering of creeper" , "Overgrown by a climbing evergreen" , "Decked with evergreen" .)
