Champagne and orange juice (6)
I believe the answer is:
mimosa
'champagne and orange juice' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for mimosa that I've seen before include "Shrub - I'm Amos (anag)" , "Tree with scented clustered flowers" , "Sensitive plant genus; so maim (anag.)" , "Type of acacia tree" , "Buck's Fizz" .)
