Prolific, lush (7)
I believe the answer is:
fertile
I believe this is a double definition.
'prolific' is the first definition.
(I know that prolific can be written as fertile)
'lush' is the second definition.

(Other definitions for fertile that I've seen before include "(Of soil) richly productive" , "Producing good crops" , "Capable of growing or reproducing" , "Fruitful" , "(Of soil) rich" .)
