Houseplants make a room cozy in the first place. But it depends on the right choice of plants! Not all are suitable for every location and we cannot recommend every houseplant and green plant without reservation. Especially if you have children and / or pets, you have to be even more careful when making your choice. There are some poisonous houseplants and some that can cause allergies or similar reactions when touched. Caution is advised!

Non-toxic houseplants

Indoor plants are all plants that are predominantly cultivated in closed rooms. In summer some can be put outside, but we are assuming room culture here. Anyone who has children or pets usually makes sure that they do not bring any poisonous plants home. The risk of poisoning is just too high. After all, there are enough harmless, yet beautiful indoor plants.

There is hardly a genus of plants that can be generally recommended as harmless because it is non-toxic. However, you are usually on the safe side with palm trees, ferns, orchids and cacti.

When buying a houseplant, you should always inquire whether it is poisonous or whether it contains substances that can have negative effects on health. Unfortunately, not all knowledgeable staff are available, so it is often better to look it up again on the Internet. It is ideal if you have the Latin name of the plant, this simplifies things and eliminates confusion (provided the name is correct).

I generally advise against spontaneous purchases of plants, regardless of whether they are indoor or garden plants. You are often tempted because there are really great plants, but I think it is better to do some research first. Anyone who has a suitable mobile phone with Internet can do so on site. If handled correctly, poisonous plants are usually not a problem. But if you have children or animals, you have to choose very carefully. Once you have finished reading, check immediately after the care instructions and the winter storage. The right conditions are important for the survival of the plants!
