Cherry laurel criticized for being invasive and toxic

Cherry laurel is facing increasing criticism in Germany due to its status as an invasive species and its toxicity. A study by the University of Bonn conducted in the Kottenforst forest area revealed that the plant, originally from Asia, is spreading rapidly and dominating local ecosystems by forming dense green walls that block light from reaching the forest floor.

Beyond environmental concerns, the plant poses significant health risks. Its leaves, fruits, and seeds are toxic to humans, children, and pets. The seeds contain glycosides that release cyanide when chewed, which can be particularly dangerous for animals like dogs that may be attracted to the sweet-tasting fruit.

Gardeners are encouraged to replace cherry laurel with native, bee-friendly alternatives for privacy hedges. Recommended substitutes include elderberry, which supports insects and birds, and hedge roses, which grow quickly and provide aesthetic value without the ecological or safety drawbacks.
