Do you know what heliophilic plants are? If in your garden or balcony only the sun arrives, you may have some, since they grow in places that are exposed for hours to the rays of the sun. They depend so much on it that when they are kept indoors or in the shade their stems quickly lengthen in search of light.
At first, this may make us happy because their growth rate is accelerating, but in reality, it is something that should concern us: when they become ethiolate they become very weak, and it is not uncommon for them to fall or bend due to not being able to support their weight. . So let’s see what and what are the heliophilic plants to take better care of them.
What are heliophilic plants?
The term heliophile derives from the Greek helium , which means sun, and phylum which is translated as lover or friend; therefore the word means lover of the sun. Therefore, heliophilic plants are those that need to be in sunny areas to be able to live, grow, and develop normally .
Contrary to the sciophiles, which are the ones that grow in the shade, our protagonists must be located in places where the Sun shines on them, for hours, and daily, so that they can perform their functions and be healthy.
In this group we find the heliotropic plants. These have a very peculiar characteristic, and that is that they move their leaves and flowers in the direction of the star king. They do it in response to the blue light emitted by the Sun, and as examples we have the sunflower or the gazania.
Types of heliophilic plants
