For example, while the fruits of the yew tree in the garden can be eaten by songbirds without any problems and the poisonous kernels can be excreted undigested, accidental consumption by humans can sometimes be fatal. A central question for many garden and house plants is therefore whether they are specifically poisonous for humans or their pets.

The wax flower: poisonous or not?
The question of the toxicity of the genus Hoya cannot be answered with a clear yes or no: Although some listings identify the plant as a supposedly non-toxic indoor plant recommended for cats, toxicological institutes warn against the toxic content of some types of wax flower. In addition, the subspecies of the "Hoya" genus, usually referred to as wax flower or porcelain flower in this country, from the tropics of Asia and Australia cannot always be easily distinguished from one another. If in doubt, you should approach such plants with the same caution that is also recommended for other poisonous plants such as yew, tree of life and ivy (almost everywhere).
If in doubt, choose non-toxic alternatives
Even indoor cats often do not even go near slightly poisonous indoor plants if they are offered an appropriate alternative with a pot full of cat grass. Out of concern for the safety of pets or small children, the wax flower should not be used in the house if its toxicological classification cannot be clarified beyond doubt. Non-toxic indoor alternatives include:
- spider plant
- jasmine
- lemon Tree
- date palm
tips
Normal handling of the wax flower by adults or teenagers who have been informed about poisonous plants and their effects is usually unproblematic and does not lead to any symptoms of poisoning if they just touch it.
