This plant, or one that resembles it, is dangerous. Identifying is not authorising: no app has the authority to tell you that you may eat or touch a plant.


The small-leaved evergreen of clipped garden hedges, which in the Peninsula is also a wild plant of limestone slopes. The wood is so dense it sinks in water, and the whole plant is toxic.

How to tell it
Small, opposite, leathery, dark glossy leaves with a notch at the tip. Four-angled twigs. A characteristic unpleasant smell when cut, which many people recognise from old gardens.
What it is confused with
No dangerous lookalikes known in the Iberian Peninsula.
What it is for
Dense, uniform wood for precision pieces, engraving and musical instruments. No food use: it contains alkaloids causing vomiting, convulsions and, at high dose, respiratory arrest, and there are poisonings of livestock that eat hedge clippings.
