Yew (Taxus baccata)

Mature yew trees can grow to 20m. The bark is reddish-brown with purple tones, and peeling. The yew is probably the most long-lived tree in northern Europe.

Look out for: the needle-like leaves which grow in two rows along a twig. Underneath, the needles each have a raised central vein.

Identified in winter by: its evergreen needle-like leaves which are present all year round.

Where to find yew

Yew is commonly found growing in southern England and often forms the understorey in beech woodland. It can be used as a hedging plant and is common in churchyards.

Value to wildlife

Yew hedges are incredibly dense, offering protection and nesting opportunities for many birds. The goldcrest and firecrest nest in broadleaf woodland with yew understoreys.

The fruit is eaten by birds, such as the blackbird, mistle thrush, song thrush and fieldfare; and small mammals, including squirrels and dormice. The leaves are eaten by caterpillars of the satin beauty moth.

Mythology and symbolism

Yew trees are associated with churchyards and there are at least 500 churchyards in England which contain yew trees older than the buildings themselves. It is not clear why, but it is thought that yew trees were planted on the graves of plague victims to protect and purify the dead, and also in churchyards to stop 'commoners' from grazing their cattle on church ground as yew is extremely poisonous to livestock.

Yew trees were used as symbols of immortality, but also seen as omens of doom. For many centuries it was the custom for yew branches to be carried on Palm Sunday and at funerals. In Ireland it was said that yew was ‘the coffin of the vine’, as wine barrels were made of yew staves.

Uses of yew

Yew timber is incredibly strong and durable. Traditionally, the wood was used in turnery and to make long bows and tool handles. One of the World's oldest surviving wooden artefacts is a yew spear head estimated to be around 450,000 years old.

Anti-cancer compounds are harvested from the foliage of Taxus baccata and used in modern medicine. Yew trees contain the highly poisonous taxane alkaloids that have been developed as anti-cancer drugs. Eating just a few leaves can make a small child severely ill and there have been some deaths linked to yew poisoning. While the red, fleshy part of the yew's fruit isn’t toxic, the seed inside it is poisonous to humans, and so are the bark and leaves.

Threats and conservation

Yew has a reputation for being indestructible, but it may be susceptible to root rot.
