Stumped with Wadsworth

O hemlock-tree! O hemlock-tree! how faithful are thy branches!
Green not alone in summer time,
But in the winter's frost and rime!
O hemlock-tree! O hemlock-tree! how faithful are thy branches!
-From The Hemlock Tree by Henry Wadsworth Longfellow

I wonder if the little Hemlock that has sprouted in this spot has any sense of the of the tree that once stood where it is now growing?  Maybe.  Maybe not.  But I like to believe that it does.

Mighty may it grow, protected as it is by what remains of it's predecessor.
