Easter flower (4)
I believe the answer is:
lily
'easter flower' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for lily that I've seen before include "Flower -- girl" , "'Behold the . . . . of the field'" , "Fleur-de-lis" , "Plant with large trumpet-shaped flowers" , "Fragrant bulbous plant" .)
