The yew is an ideal ornamental shrub to form beautiful hedges or for topiary art. Because of its exceptional longevity, it has long been associated with death, as a link between heaven and earth. Therefore, because of this symbolism, it is often found in cemeteries. Yew is poisonous except for the aril pulp which is the red berry produced by female specimens. The seed and needles of yew are also poisonous. So be very vigilant.

The yew, a conifer with an exceptional lifespan
Can reach up to 20 meters high, the yew ( Taxus baccata ) is a non-resinous conifer found in Europe and North America. It is a tree whose lifespan is among the longest. By way of illustration, the oldest yew in France is found in Brittany (Pommerit-le-Vicomte), which is estimated to be between 1,500 and 2,000 years old. The oldest yew in Europe , 2000 years old, is located in Scotland. However, yew forests have become rare in Europe due to the toxicity of the tree. A stand of yews is called ivaie .
The yew has a straight and robust trunk crowned with branches from its base. Its shape is rather irregular. This evergreen conifer consists of long, flat, non-prickly needles of dark green color.
The poison of yew is taxine , a very dangerous alkaloid . According to this specialized site on trees , the Gauls used this poison for hunting and called it Ivos , which would have given its name to the yew tree .
Are you considering planting a hedge? The yew is a hardy , slow-growing conifer that is valued for its dense foliage and ease of maintenance. It supports negative temperatures down to -15°C. Another advantage is that it tolerates pollution well. For a hedge of about 1m80 to 2 meters high, respect a distance of 80 cm to 1 meter between the plants. Indeed, as it grows, the yew takes up space and it is therefore necessary to anticipate its future circumference which can exceed 4 meters. As an isolated subject, the Taxus baccata is also a good candidate for topiary . After planting, water regularly for two years to facilitate rooting.
The yew is a robust tree that appreciates:
- Cool ground and humid atmosphere
- Sun or shade exposure
- Acidic or calcareous soil
The female yew produces edible bright red berries (arils). Be careful, with the exception of the arils, all parts of the yew are toxic : the bark, the needle and the seed contained in the fruit. Only the carmine pulp can be eaten when ripe from September to December. The aril has a sweet and mucilaginous flavor which allows it to be eaten in jam.
Never forget that the seed is poisonous . This is why the consumption of yew fruit is not recommended. Be very vigilant and if in doubt, do not eat the fruit.
The berry is also popular with birds, which do not digest the seeds and scatter them. Mammals and especially horses are also very fond of berries. However, a single bite is fatal to equines, as they ingest the seed and are highly sensitive to taxine.
Yew pruning and care
For a hedge, prefer pruning in early spring (stimulation pruning) or in the fall. In topiary, prune lightly in August . However, remember to pick up all pruning debris to avoid accidental ingestion.
The yew is a robust tree that does not fear disease. Although it is not very demanding in terms of maintenance, it does however need special attention with regard to watering at the start of its life: be regular the first two years and in the event of drought.
