The cotoneaster is a popular ground cover that is often planted in rock gardens, on slopes, embankments and roads. Their bright red fruits attract berry friends. But beware: This plant literally has it all!
Toxic - yes or no?
The cotoneaster is poisonous - regardless of whether as a bonsai or ground cover. It is considered slightly poisonous. The reason for this is, among other things, their content of hydrocyanic acid, which is highest in their fruits. Depending on body weight, symptoms of poisoning occur from a quantity of between 10 and 20 fruits.
Hydrocyanic acid causes mild poisoning. It impairs cellular respiration and causes internal asphyxiation. Symptoms can be the following:
- nausea
- Vomit
- lip swelling
- stomach ache
- burning in the mouth
Which parts of plants contain toxic substances?
Toxic substances in cotoneaster include prunasin and amygdalin (a glycoside containing hydrocyanic acid). All parts of the plant, both leaves and bark as well as flowers and fruits contain one or both of these active ingredients and can have a toxic effect on the body.
The fruits have the highest poison content. The seeds contained, which can be used for propagation, are also poisonous. Be careful when handling this plant!
tips and tricks
As a precaution, the cotoneaster should not find a place in the garden if smaller children live in the household and like to play in the garden. The red and berry-like fruits in particular quickly tempt you to snack on them. In an emergency: Administer 1 g of medicinal charcoal/activated charcoal per kg of body weight to bind the toxins.
