Blue-flowered plant (6)
I believe the answer is:
scilla
'blue-flowered plant' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for scilla that I've seen before include "Blue spring flower from small bulb" , "Lily's relative" , "One of Lily's family" , "Plant of lily family with small blue flowers" , "Blue flowered plant of lily family" .)
