A cactus is a common plant, but what category does it belong to? Is it a flower or another type of plant? These questions have long puzzled people. In this article, we will answer these questions one by one and take an in-depth look at the growth habits, propagation methods, and care tips for cacti.
I. Classification and Naming of Cacti
A cactus is a type of succulent plant and belongs to the Liliaceae family. Its scientific name is Cactaceae, derived from the Greek word "kaktos." Cacti are named for their shape and appearance, resembling small spheres covered in sharp spines.
II. Growth Environment of Cacti
Cacti are native to the Americas, including North, Central, and South America. Due to their strong adaptability to arid environments, they have now been widely introduced to all over the world. Cacti prefer sunny, dry, and well-ventilated environments, with the most suitable growth temperature being 20°C-30°C.
III. Appearance Characteristics of Cacti
The characteristics of a cactus are its spherical shape, sharp spines, and fleshy stems. Their leaves have degenerated; due to the dry and sandy windy environment of their growth, they have evolved into fleshy stems to store water. The sharp spines of cacti protect them from predators.
IV. Reproduction Methods of Cacti
Cacti can be propagated in various ways, such as by seeds, cuttings, and stem division. The most common method is propagation by cuttings, where a piece of the cactus's stem is inserted into the soil. Once it takes root, it can be potted up individually.
V. Care Tips for Cacti
A cactus is an easy-to-manage plant, but some details need attention. For example, you should choose soil with good drainage and let the soil dry out completely after each watering to prevent root rot from waterlogging. At the same time, control the amount of fertilizer and exposure to light to avoid over-fertilization and insufficient light.
VI. Growth Cycle of Cacti
The growth cycle of a cactus varies by species. Some species take only a few years to mature, while others take more than ten years to bloom. Generally, the growth cycle of a cactus is 3-5 years, during which they will gradually grow larger and form a complete plant.
VII. Common Misconceptions in Cactus Care
When caring for cacti, many people easily make some mistakes. For instance, they believe that cacti can remain in a state of drought for a long time, which can actually cause their stems to turn yellow or crack. Some people also place cacti in dark, humid environments, which can lead to fungal infections and affect their growth.
VIII. Spiritual Symbolism of Cacti
In addition to being a beautiful plant, the cactus also has profound spiritual symbolism. In both Eastern and Western cultures, cacti are seen as symbols of resilience, courage, and perseverance. Their sharp spines also symbolize a powerful ability to defend oneself.
IX. Application of Cacti in Landscaping
Due to their diverse shapes and rich flower colors, cacti are widely used in landscaping. For example, in dry regions, cacti can be used to decorate courtyards and flower beds. In sunny areas, cacti can be planted in outdoor gardens, becoming a beautiful sight.
X. Beauty Benefits of Cacti
Cacti also have certain benefits in the field of beauty. They can help purify the air, regulate humidity, and effectively remove radiation. In addition, cacti contain many nutrients beneficial to the skin, such as vitamins C and E, which can moisturize the skin and delay skin aging.

In some folk cultures, cacti are also regarded as symbols of attracting wealth and good luck. For example, in traditional Chinese culture, cacti are often placed in homes or offices to seek prosperity and success in one's career. In Mexico, the cactus is considered a symbol of happiness and prosperity.

Besides being used for decoration, beauty, and symbolism, cacti have other clever uses. For instance, in desert areas, cacti can be used to make water containers or as medicinal materials. Their fruit can also be used as an ingredient to make various delicacies.
