Yew-tree, yew-tree, true to your kind,
In churchyard you are found;
O ivy growing ivy-like,
You are found in the dark wood.
O holly tree of shelter,
Bulwark against the winds;
O ash-tree, very baleful one,
Haft for the warrior's spear.
O birch-tree, smooth and blessed,
Melodious and proud,
Delightful every tangled branch
At the top of your crown...
~excerpt from a poem on their legend,
as found in the White Goddess
