When we talk about living beings, we often divide life forms, animal and plant life into two categories, giving it a purely passive role, excluding these creatures from interacting with the world around them. Instead there are plants that actively "live", passing from the role of prey to that of "hunters". And it is precisely the case of carnivorous plants, plants that have always aroused interest and amazement, fear and disbelief since our childhood. We must reassure ourselves of the fact that there is no monstrous and terrible plant, dangerous to humans, but rather beautiful and fascinating plant species, which at most can capture small insects, or in the worst case small animals like frogs or mice. Carnivorous plants are present all over our planet in as many as 600 different species, from South Africa to Europe, from Indonesia to the United States.
Even in our country, Italy, there are several species of carnivorous plants, even if they are among the plants threatened with extinction.
These wonderful plants have studied and developed an incredibly advanced system of capture and digestion, so as to be able to absorb the essential nutrients to live from their prey. Carnivorous plants grow mainly in peat bogs, on lands that are extremely poor in nutrients such as nitrogen, and are therefore forced to feed thanks to their "hunting". As we said before, there are just 600 species of carnivorous plants, all very beautiful and interesting; some use "snap" capture systems, such as the now-famous Dionaea, one of the most popular carnivorous plants, or secreting viscous substances that can trap insects on their leaves, or even creating real traps without a way out called "ascidi".
Introduction to carnivorous plants: Cultivation techniques
Many have attempted the cultivation of these plants, but death has probably occurred a few days after the purchase. The main cause is the lack of information given and the beliefs about these plants. 90% of carnivorous plants are highly sensitive to limestone or tap water, which leads to certain death within a short time. Another problem is often the lack of water, or the low exposure to sunlight. Carnivorous plants love large amounts of water and plenty of sun exposure, while our intuition would advise us to give little water and keep them away from the sun. Also the substrate to be used is very important, and it is necessary to use exclusively sphagnum peat, because it is to use simple or enriched soils, it would mean killing the plant, not used to rich soils that would cause the rotting of the roots in a short time
