Yew Tree

How poisonous is a yew tree? Very! A few leaves can kill people and animals.

The Yew tree (Taxus Baccata) is most commonly found in Southern England. The yew tree’s leaves, seeds, and bark can be poisonous to people and livestock. For this reason, many yew trees are planted in graveyards, away from the general public and animals. 

The Yew tree is one of the longest-living species in Europe, and it can grow up to 20 meters. Its bark boasts a blend of red, brown, and purple tones, and its needle-like leaves grow in rows along its branches. 

The Yew tree’s leaves are small, straight, and dark green, with a green-grey tone on the underside. The Yew is dioecious,  meaning that its male and female flowers grow on separate trees. Males flowers have a modest white-yellow structure, and female flowers sport a scaly appearance, maturing to resemble acorns with age.

While Yew trees have strong associations with doom and gloom, they’re an essential tree for many animals across Southern England.
