Ground skin, this small and exquisite plant, often grows in corners where people accidentally see it. Especially in damp environments, they can thrive and bloom elegant flowers. But, you know what? Whether the ground skin is a perennial or an annual plant is still a mystery. This article will focus on this topic.

What is a skin?
Kochi, also known as crosswort, calla lily, privet fruit, etc., is a general name for Kochi plants in the Rubiaceae family. They have a spreading nature, often covering the ground and producing elegant flowers.
Characteristics of ground skin The ground skin has strong adaptability and can survive and grow in extreme environments. In addition to their tenacious vitality, they also have another distinctive feature: they can reproduce from underground roots. This breeding method brings great convenience to the skin.

Ground skin is a perennial plant The view that ground skin is a perennial plant is mainly based on their strong reproductive ability. They can reproduce from underground roots, which means that even if the upper part is destroyed, underground roots can continue to grow.
Ground skin also has an annual performance. Although ground skin has a strong reproductive ability, judging from its growth cycle, they also have an annual performance. Within a year, the ground skin will go through several growing seasons and die at a certain period of time, and then reproduce through underground roots and other methods.
Factors influencing the life cycle of Kochi There are many factors that affect the life cycle of Kochi, the most important of which is environmental factors. For example, temperature, light, humidity, etc. In addition, there are factors such as the nutritional status of the plants and soil quality.

The reproduction methods of the skin There are three main reproduction methods of the skin: seed reproduction, rhizome reproduction and plant reproduction. Among them, rhizome reproduction is the most common.
Root reproduction of kosher The root reproduction of kosher means that the roots produced in their underground parts can grow new seedlings. This breeding method can allow the rapid spread of ground skin in the same area.
The ramet propagation of kosher The ramet propagation of kosher means that they produce small plants from the base of the plant, and these small plants can grow into new plants. This breeding method also provides a convenience for the breeding of ground skin.
Seed reproduction of koji The seed reproduction of koji means that they bloom and set seeds, and then reproduce by spreading seeds. Although this reproduction method is inefficient, it has a good effect on the spread and dispersion of seeds.
Where is the suitable place to grow skin?
Ground skin likes to grow in moist soil and cool environment. They can grow in forests, river banks, watersides and other environments, and can often grow very luxuriantly.
How to maintain the skin?
The maintenance of the skin mainly includes measures such as maintaining moist soil, regular fertilization, and preventing pests. In addition, weeds should be cleared in time to keep the health of the plants.
The effect of ground skin on the environment The effect of ground skin on the environment cannot be underestimated. They can maintain soil stability, prevent soil erosion, absorb waste gas and reduce noise.
The effect of koji on humans Although koji is not the main medicinal plant, it has certain medical and edible value. For example, they can treat some symptoms such as chest distension and diarrhea.
Conclusion Kochi is a plant with tenacious vitality and plays a very important role in nature. Although it is still a mystery whether the ground skin is perennial or annual, we can better understand this excellent plant by discussing its growth cycle, reproduction methods, and suitable environment.
