Rife with life (4)
I believe the answer is:
lush
'rife with life' 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 "Lavish - boozer" , "Of growth, profuse and abundant" , "Verdant" , "one mortal too often" , "Attractive" .)
