Plants in the house

The plant world is much, much more than the plant we have on our balcony or the flowers we see in our lawns. It is part of that extraordinary phenomenon that is nature, with its evolutionary history and the ability to generate life. Man has always had a certain relationship with the reality that surrounds him, which, despite the social changes that led us to build cities (where nature is almost totally replaced by buildings), remains very natural, also because nature is the only one capable of positively influencing the human soul. And so the only glimmer of nature left in our homes is the plants that many of us grow out of pure passion. They are useful for growing some food of our liking (such as basil, parsley, a fresh tomato and similar things), but also for the decorative ability and the undoubted aesthetic appeal of almost all floral species. Some of them, obviously, are more beautiful than others and at the same time they demonstrate to have adaptation characteristics that make them suitable for living in our apartments and for which they are commonly referred to as house plants “.

Tropical plants

Probably some of our readers will be surprised that many of the most popular houseplants are clearly of tropical origin. At first glance it seems strange, but we must consider some climatic characteristics of the tropics that actually resemble those of our apartments. First of all we could set up the discussion of humidity, with that of the tropics and their forests which is proverbial, while in our apartments it is quite high due to the human presence (with relative sweating and breathing), with cooking operations, showers, bathrooms etc. Not only that, in our homes there is rarely direct sunlight, and this is very similar to tropical forests, where large plants (tall and with large crowns) cover most of the light to the lower plants, which then are the ones we place in our apartments. To all this, which already helps to clarify how many tropical plants manage to live in our apartments with a certain ease, we must add the spirit of adaptation common to all plants, an important feature that has allowed the evolution and survival of plants to millions of years to the present day.


One of the tropical plants that finds the most commercial success and therefore that we can find in a large number of homes is the Caladium. Probably the name will not say much to many people, also because it is the more vulgar name of the “caladium” species, and also because the plant is far more famous for its appearance than for its name. The Caladio is a plant of the same family as the Calle, with which they share a very interesting detail, namely the inflorescences. We use this term because the typical flowers of Calle and Caladio (with an evident central element of yellow color around a single crown with a slightly lowered tip on one side) are nothing more than inflorescences, composed of the real flower – which is the central yellow part – and a degenerated leaf which is the part of the various colors that is around. But the most appreciated and known characteristic of Caladio are undoubtedly the leaves, which are often decorative due to their large size, elegant and very simple shape and also for the various chromatic motifs with which they are colored in addition to the intense green of the base.

Characteristics and cultivation technique

We have already specified which is the most famous characteristic of the Caladio, that is the very beautiful and decorative leaves (also because, we specify, the Caladio blooms very very rarely in the apartment). They arise from the central part of the leaf, which is an underground rhizome that acts both as a root and as a reserve of nutrients, perfect occasion and as a stem of the plant. In fact, the large leaves arise directly from the ground, at the top of long petioles that sprout from the rhizome, therefore apparently they come from the ground. As far as the cultivation technique is concerned, we can say that these are not difficult and particularly pressing operations, but that in their simplicity they must be carried out to guarantee the survival of the plant. First of all, the Caladium must be watered only from March to September, while in the autumn period the irrigations must be completely suspended and the plant must be kept in a warm and dark place, also because all the leaves will have fallen and only the underground rhizome will remain. Another feature to take into consideration of Caladium is the fact that it likes a high rate of relative humidity (after all, it is native to tropical forests and therefore it could not be otherwise), which can be reached in summer with vaporization on the leaves, while during all year round it is good to keep the vasoninnun saucer with gravel and a drizzle of water, so that the processing always keeps the air moist. Then the same way you have to be careful because the Caladio wants a temperature of just under twenty degrees,
