Crocus cousin (4)
I believe the answer is:
iris
'crocus cousin' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for iris that I've seen before include "A flower; spirit conjured in Tempest" , "Eye part or pretty flower" , "Plant - part of the eye" , "Lily" , "Fleur-de-lis" .)
