Crossword Genius

Green but sensible (4)

Ross

I believe the answer is:

sage

This clue is a double definition.

'green' is the first definition.
(sage green is a kind of green)

'sensible' is the second definition.
(thesaurus)

'but' acts as a link.

(Other definitions for sage that I've seen before include "Fragrant herb having wisdom" , "Wise man - flavoursome plant" , "Seasoning for the wise one" , "cheesemongers associate with Derby" , "Oracle; herb" .)

I've seen this clue in the Evening Standard.
