Flower in shade (6)
I believe the answer is:
violet
I believe this clue is a double definition.
'flower' is the first definition.
(thesaurus)
'shade' is the second definition.
(I've seen this before)
'in' acts as a link.
(Other definitions for violet that I've seen before include "Girl's name - colour" , "Colour midway between red and blue" , "Seldom" , "Mauve" , "Rainbow colour; flower" .)
