A heavenly garden (4)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
eden
'a heavenly garden' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for eden that I've seen before include "Perfect place" , "Our leader once" , "The original garden?" , "Genesis location" , "heavenly spot" .)
