Cherry Laurel Branch

The fruit is a small cherry 1–2 cm broad, turning black when ripe in early autumn can have the scent of almonds when crushed.

 

Leaves, fruit and seed may cause severe discomfort to humans if ingested.

 

The seeds contained within the cherries are poisonous like the rest of the plant, containing cyanogenic glycosides and amygdalin.

 

This chemical composition is what gives the smell of almonds when the leaves are crushed. Laurel water, a distillation made from the plant, contains prussic acid and other compounds and is toxic.

Why Is Cherry Laurel A Problem?

Cherry Laurel is an alien (non-native) invasive plant, meaning it out-competes crowds-out and displaces beneficial native plants that have been naturally growing in Ireland for centuries.

 

Its rapid growth, coupled with its evergreen habit and its tolerance of drought and shade, often allow it to out-compete and kill off native plant species. It is spread by birds, through the seeds in their droppings..
