It is a herbaceous plant that can be seen everywhere in the countryside. It has small blue flowers and lanceolate leaves, and it is easy to identify on the grassland. Its name is Commelina communis, also known as the Blue Cicada Grass or Bamboo-joint Vegetable. In folk, whenever there are symptoms such as wind-heat cold and sore throat, people will pick the whole herb and boil it to make a decoction for drinking. At the same time, if people are troubled by athlete's foot, they can also boil the herb in water and use it to soak their feet, which can effectively remove the odor and bring a fresh and comfortable feeling to the feet. Therefore, it is praised as an indispensable "treasure plant".
Commelina communis is an annual spreading herb, mostly distributed in places such as Yunnan, Sichuan, and Gansu in China. It is also distributed overseas in regions such as Vietnam, North Korea, Japan, and the Far East of Russia. In terms of maintenance, it can be propagated by sowing, cutting, and division. It is recommended to plant it in a small courtyard or in a field. There are not many requirements for the soil because it can thrive both in poor soil and in relatively moist places. If you plant it in a pot, it is recommended to mix leaf mold, garden soil, and river sand in a ratio of 3:2:1 to prepare the soil.
When maintaining it indoors, the suitable growth temperature for Commelina communis is between 15 and 25 degrees Celsius. It has a certain degree of cold resistance, but when the temperature is too low in winter, it is still necessary to take good warming measures to prevent the plant from being frostbitten. As for the light, it is recommended to place it in a place with bright light but without direct sunlight, such as by the windowsill in the living room. In maintenance, if there is insufficient light, the plant will grow thin and weak, and if the light is too strong, the leaves will easily turn yellow.
Commelina communis likes a moist environment. Therefore, in terms of watering, you can water it when the surface of the soil turns slightly white, and water it thoroughly each time. When the air is particularly dry, it is necessary to frequently spray water mist around the plant to increase the overall air humidity. This can make it grow more vigorously and the flowers more beautiful.
Daily maintenance of flowers and plants is inseparable from fertilizers. During the growth period of Commelina communis (from July to September), it is necessary to fertilize it regularly. At this time, compound fertilizers or thin liquid fertilizers are recommended, and fertilize once every half a month to about 20 days, which can promote growth and flowering. In addition, fertilization should be suspended when the temperature exceeds the suitable growth temperature.
