Departs; foliage (6)
I believe the answer is:
leaves
I believe this clue is a double definition.
'departs' is the first definition.
(I know this)
'foliage' is the second definition.
(I've seen this before)
(Other definitions for leaves that I've seen before include "Rocket, for example" , "They are found on trees and in books" , "exits" , "Pour hot fat over (meat)" , "''All the ... are brown'' (California Dreamin')" .)
