With the first warm rays of sunshine, Mother Nature awakens and sets the first colorful accents in the garden with her signs of spring. However, if you share your garden with dogs, cats, etc., you should avoid some plants. No matter how beautiful they look, flowers and plants sometimes contain toxic ingredients that can cause irritation and serious symptoms of poisoning. But which plants are dangerous and what can you do to help your beloved four-legged friend immediately?

Things to know about poisonous flowers in brief
Quite a few “poisonous beauties” are at home in our local flower pots and gardens. Many of them are even extremely popular. Some of the most famous poisonous flowers in our gardens and living rooms are:
- lily of the valley,
- the snowdrop,
- the delphinium,
- the thimble,
- the golden shower,
- Oleander,
- the autumn crocus,
- the cup primrose
- and the belladonna lily.
The poisonous flowers in our home or garden pose the greatest danger to small children. After all, they are always tempted to put everything in their mouth or try it. And most poisonous flowers look enticingly colorful and exude a pleasant scent. That's why it's important, especially with small children, to pay close attention to which flower they pick from the meadow! But many adults rarely know exactly which plants are poisonous and what a plant's poison can do.
Example: Golden shower
The laburnum, for example, is a beautiful shrub that makes every garden shine with its bright yellow flowers. But as beautiful as the golden shower is, it is also dangerous. When ripe, the seeds of this shrub are reminiscent of beans in shape. And this part of the plant is also the most poisonous. Even small amounts of the substance it contains can cause nausea, vomiting and tremors. There are even cases where ingesting parts of the plant has resulted in death. In these cases, respiratory paralysis or total circulatory failure occurred.
Example: Foxglove
Another beautiful, yet poisonous resident of our gardens is the foxglove. And most people also know that foxgloves are poisonous. But very few people know exactly how poisonous it is. There are of course different types of thimbles. They differ in the shape of the flowers, stems and leaves. However, all foxglove species have one thing in common: they are all highly poisonous. Even small amounts of foxglove poison can cause nausea and vomiting. This condition can last for several days. Even worse, however, are the consequences that the poison has on the heart and circulation. The pulse falls continuously (down to 20 beats per minute) while the blood pressure rises. Cardiac arrhythmias occur and this can even lead to cardiac arrest, i.e. death.
Example: cup primrose
The cup primrose is one of the most poisonous houseplants. It is not for nothing that it has the appropriate nickname: poison primrose! If you have small children or pets, you might want to avoid putting this flower in your home. The cup primrose has small glandular hairs on its stems through which it secretes a poisonous secretion. That's why you should be particularly careful when removing wilted leaves, for example, and avoid contact with skin. If this toxic secretion comes into contact with the skin, it can cause irritation, swelling, itching, blistering and pain. The symptoms actually get worse every time you come into contact with the secretion.
