All your questions about ivy
Is ivy toxic?
Yes, ivy is toxic from head to toe. Three cases in particular are worth explaining:
- The fruits of adult ivy are berries that look a little like blueberries. These berries are toxic, as they contain saponosides. Their taste is not at all pleasant. Take care to keep children away from them or at least informed of the danger. On the other hand, these berries are not toxic to birds, which are particularly fond of them in late winter. On the other hand, most ivy plants, especially houseplants, are not mature, so they don’t produce berries.
- Stems and leaves can be nibbled by herbivorous domestic animals. This can lead to cardio-respiratory problems, with the risk of death if consumed in large quantities. Fortunately, our pets are not at all fond of ivy.
- The third case is more common. Ivy is also an allergen. Handling ivy in large quantities can lead to contact dermatitis (skin irritation, hives, even asthma). Fortunately, it’s easy to protect yourself by simply wearing gloves.
