Usksider asked me an interesting question the other day. Why are there so many yew trees in cemeteries? It’s not just in Britain either – they’re popular throughout Europe.
In ancient Greece and Rome, the yew was dedicated to Hecate, goddess of the Underworld and Magic. The torches of the Eumenides (goddesses of Vengeance) were also made of Yew.
But the main reason for yews being so closely associated with death is its toxicity and dark colour. It is also an evergreen, and these are usually all associated with death, and perhaps because it can be so long lived (some yews can grow for over 1,000 years) it has also come to represent immortality.

What is interesting is that the tradition persists. I noticed recently there was a yew tree growing in the cemetery of a church in Boston, Lincolnshire, which was built no more than eighty years ago.
