Verdant meadow frantically evacuated (5)
I believe the answer is:
leafy
'verdant' is the definition.
(I've seen this before)
'meadow frantically evacuated' is the wordplay.
'meadow' becomes 'lea' (a lea is a grassy area).
'evacuated' suggests removing the centre (internal letters are evacuated from the word).
'frantically' with its centre removed is 'fy'.
'lea'+'fy'='LEAFY'
(Other definitions for leafy that I've seen before include "Full of foliage" , "more shady places?" , "Like the better class suburbs?" , "Epithet applied to suburbs" , "Abounding with trees" .)
