It's heavenly under a tree (7)

I believe the answer is:

sublime

'it's heavenly' is the definition.
(I've seen this in another clue)

'under a tree' is the wordplay.
'under' becomes 'sub' (I've seen this before).
'a tree' becomes 'lime' (type of tree).
'sub'+'lime'='SUBLIME'

(Other definitions for sublime that I've seen before include "Transcendent" , "Exalted; awesome" , "Glorious; supreme" , "Heavenly" , "Magnificent" .)

I've seen this clue in The Globe and Mail and The Irish News.
