Die stille Symphonie: Wie Pflanzen miteinander kommunizieren

The Silent Symphony: How Plants Communicate with Each Other

In the quiet world of plants, far from the hustle and bustle of human civilization, subtle but profound communication takes place. These silent conversations between plants are a fascinating phenomenon that scientists have been studying for decades and still hold many mysteries. Today we take a closer look at how plants interact with each other, sing, and respond to their environment.

The language of plants

Plants communicate in different ways: through chemical, optical and even acoustic signals. One of the best known examples is the secretion of chemical substances. When a plant is attacked by pests, it can release certain chemicals that warn neighboring plants. These "warned" plants then start to activate their own defense mechanisms even before the pests reach them. A classic example of this is the acacia tree in Africa, which releases tannins to protect itself from grazing animals.

Optical signals and the shining example

Plants can communicate not only through chemical substances, but also visually. Research has shown that some plants can change their color to communicate information about environmental conditions to other plants. These changes are often so subtle that they can only be perceived with special instruments.

The singing plants

A particularly fascinating aspect of plant communication is acoustic interaction. Studies have shown that plants can respond to frequencies that are inaudible to the human ear. There are reports of "singing" plants that respond to external stimuli through vibrations. One example of this is a study that found that young corn plants produce cracking sounds at a frequency of around 220 hertz, which was interpreted as a response to water shortages.

Stories from the plant kingdom

One of the most touching stories of plant communication comes from Japan. After the 2011 tsunami, botanists observed how certain plant species began to change their flowering time, a phenomenon that was probably a response to the changing soil conditions. This adaptation may have been a form of communication, a silent signal to other plants to adapt to the new circumstances.


Communication between plants is a wonderful example of the complexity and sophistication of nature. Whether through chemical signals, color changes or the production of sound, plants have developed their own methods to survive and thrive. This silent symphony playing in our gardens and forests is proof that life - even at its quietest - is incredibly dynamic and interconnected.

In this blog post, we have only scratched the surface of a deep and complex topic. Plant communication remains an exciting field of research that will continue to surprise and inspire us the more we learn about it.
