Covered with lush green grass or vegetation (7)
I believe the answer is:
verdant
'covered with lush green grass or vegetation' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for verdant that I've seen before include "Leafy" , "Rather green" , "Unsophisticated" , "Green like grass or fields" , "Covered with lush green grass or vegetation" .)
