Venus Flytrap - Thunderstorm Flies and Mosquitoes
Venus flytrap (scientifically - Dionea flycatcher), is the most famous plant “predator” on the entire North American continent, and the only species in the genus. It belongs to the Rosyanka family, almost all of whose representatives are endowed with the ability to eat animal food.
Venus flytrap is a peat bog inhabitant. All its leaves are located rosette, lying close to the ground, and upward only the flower arrow rises. The leaves of this predator perform a dual role. Firstly, they, like the green leaves of other plants, are carbon assimilators, and secondly, they are under the responsibility of extracting nitrogenous food, since the roots of this plant, due to the poverty of peatlands with nitrogen, cannot deliver sufficient quantities. The adult Venus flytrap, which catches and successfully assimilates flies, mosquitoes and other insects, usually does not exceed 15 cm in height. In spring, it blooms with large white flowers located on long peduncles.
Despite the fact that the Venus flytrap grows in swamps, it practically does not tolerate stagnant air, requiring at least a few hours of direct sunlight for normal growth. In the winter months, there is a period of rest, and the vital activity of this plant falls. At this time, it is preferable for her to low temperatures and the absence of bright light. The Venus flytrap has four growth cycles. In the spring, coming out of peace, she releases rosettes of leaves and sometimes a few stalks with flowers. In the summer, a few more leaves appear on it, and various leaves: new leaves appear on top of the lowest leaves that are lowered to the ground and stand high on stalks above the ground. It is from them that traps are subsequently formed. With the onset of cold weather, only the bottom rosette of leaves remains on the plant - the rest die out.
Many people are mistaken in the belief that caring for Venus flytrap is difficult and impossible to grow at home. However, this is not the case, and this is evidenced by the growing popularity of this beautiful predator. Venus flytrap, care of which involves a constant humid air and cool content, is an excellent culture for non-solar window sill.If in the summer it is prone to the scorching sun, without depriving the light, then Dione will delight with its bright leaves. At the same time, it is also necessary to observe the not very hot temperature regime, since the Venus flytrap is a plant sufficiently hardened, capable of withstanding even light frosts. Considerable moisture in the air is very useful for it, so it is preferable to cultivate it in a greenhouse, not forgetting to feed it from time to time with a flower fertilizer. It is preferable to buy a relatively young plant in stores, because the flycatcher seeds quickly lose their germination. Leaf cuttings root well when rooted in sphagnum.
Dionea - the hunter
The principle of operation of the Venus flytrap trap is very simple: in its two valves, remotely resembling the valves of the shells of mollusks, there are glands inside that produce nectar that is very pleasant in smell. Several trigger hairs grow on the inner surface of the valves, and if an insect, engulfing nectar, accidentally touches them, the trap will begin to slam.
