The composition of pitcher plant is different from that of many plants. It has a peculiar organ, the insect catching cage, which looks like a pocket with a leaf like cover on it. The whole cage is equivalent to its leaves, while the leaf like one is actually its petiole. Its flowers are very small, with light fragrance in the daytime, and strong odor in the night.
The pigsty grassland is produced in the tropics and subtropics. It has a high demand for the growing environment. It needs to grow in the environment of high temperature and humidity, and at the same time can receive the scattered light. Some grow in the dark forest, or on the cliff.
The cage is a special organ of pitcher plant grass. Its main function is to catch insects. The top of the cage is the cage mouth, surrounded by lips, which secrete slippery honey, which can attract insects and make them fall into the cage. There is digestive fluid in the cage, which can drown and digest insects. Part of the digestive fluid is sticky, which can ensure that insects cannot escape.
In addition to its ornamental value, pitcher plant grass can also be used as medicine. It can clear the lung and moisten the dryness, and has the effect of relieving cough.
