The stories that I have are;-
The oldest humane corpse found had a Yew tree spear in his possession.
A post of Yew will outlast a post of Iron.
Pagans worshipped the tree because it has the power to give both life and death, apparently the berrys are not poisonous whilst the green foliage is ?? That is one of the reasons why the Yew is grown in burial grounds or church grounds because animals are not generally grazed in these areas
(but not always)
If a church has a Yew tree, then there is a good chance that the site was Pagan before it became Christian.
In the middle ages the demand for Yew was so great, archery etc, that the Crown ordered many areas to grow Yew and churches again been a safe place from animals.
Many people in history ate the leaves (like nuns) as suicide rather than be raped or murdered.
I think I will plant one in my garden to keep dogs off from leaving their trade marks !
The oldest Yew in the Uk is in Scotland ? Reputedly 2000 year old.
The oldest Yew is in Spain at 3000 year old ?
