OK Maisie it was a silly point - I'll give you that the Scots in their wisdom call the harebell the bluebell, but most people this side of the pond if you said the name bluebell would think of the woodland carpeter, and Day Lewis is definitely not referring to that plant. The harebell is found more often in the west of Ireland, which agrees with the poem. But some lovely poetry for us to mull over..... Mary
