Fat plants

Sarracenia flava


The Sarracenie are plants originating from North America, more precisely distributed between the United States and Canada, and eight pure species are part of this genus, whereas hybrids exist indefinitely!
Sarracenia has long and vertical "tube" leaves, that is, in the shape of an inverted cone with an opening at the top, surmounted by a small cover called "opercolo". The underground part is composed of a "rhizome" similar to a fleshy tuber, and several roots not extremely thick.
This plant can reach a height of one meter and form dozens and dozens of pipes, called "ascids",
able to attract and contain numerous prey. Its capture system is very simple, in fact the prey is attracted by the beautiful colors that this plant creates on its pitchers, and by the production of a dense and perfumed nectar that covers its entrance. Our unfortunate therefore, intent on collecting the "honey", enters more and more towards the internal area of ​​the trap, which appears as a smooth and waxy wall, which inexorably will cause the victim to slip into the deepest and narrowest part of the ascent. At this point, the insect is not able to fly or even climb up to the exit, due to a thick down-turned down, which serves to favor the descent, but to make the ascent impossible. At this point the insect will be digested and absorbed by the plant, which will provide useful nourishment and benefit.
The eight species of Sarracenia differ greatly from each other, both as colors and as forms.
Sarracenia psittacina and Sarracenia purpurea, for example, are the only two species that possess the horizontal lying down and not vertically like all the others.

Sarracenia flava: Cultivation techniques

The cultivation of these plants is rather simple, if you follow as for all carnivores, some important precautions.
First of all it is important to give abundant quantities of water from the saucer, which we will always leave with at least two centimeters of water, distilled or rainy. The exposure must be in the sun, as long as possible. If the temperatures should be extremely high, then we can lightly shade the plant. The usually favorable growth periods are spring and autumn, but many Sarracenias grow well even in summer.
Sarracenia is a plant that lives in temperate zones, and for this it necessarily needs to rest during the winter, and it is therefore necessary to subject it to very cold temperatures. To do this, just leave the pot outside, without water in the saucer, but only checking that the substrate is moist. There is no need to worry if the temperature drops well below zero, because this plant can withstand very cold temperatures.
For the repotting it is necessary to wait for the month of February, when the plant is almost ready to resume the vegetative period. We will therefore use a larger vessel than the previous one, and we will use a substrate composed of a part of sphagnum peat and a part of perlite. It is also possible to add a small amount of vermiculite, but not in doses above 10%. It is important, during repotting, not to excessively handle the roots, but try to repot the entire loaf of soil, perhaps removing only the excess peat.
