Cotton rose hibiscus - different colored flowers on a single tree? What does the flower language of the cotton rose hibiscus mean?
Known as the "drunken beauty" of winter, its flower language carries meanings of wealth and good fortune, independence and confidence, and it is also a flower with medicinal and culinary value. Its name is "cotton rose hibiscus." In appearance, it has inverted triangular petals, and its flower color can change three times in a single day depending on the growing environment or light intensity.

In the world of traditional Chinese medicine, the cotton rose hibiscus has effects such as treating red and swollen eyes, cooling blood and stopping bleeding, and fighting cancer. It is also used in cellulose textiles, the paper industry, and more. It can truly be said that the entire plant is a treasure. It originates from Chongqing, China. It is a woody plant in the genus Hibiscus of the mallow family. In terms of care, it prefers a warm and humid climate, with an optimal growing temperature of 25 to 28 degrees Celsius. If the ambient temperature falls below 18 degrees Celsius, it will exhibit slow growth. Normally, it is recommended to place it on a windowsill with sunlight, because it enjoys a sunny environment.

As for soil, the cotton rose hibiscus is not demanding and can even grow in poor, thin soil. When changing the soil, it is best to choose well-draining and fertile leaf mold, garden soil, and sandy soil, or mix these three types of soil in proportion.

As for watering, it is drought-tolerant but not waterlogging-tolerant. Keeping the soil slightly moist is best. During summer when temperatures are high and humidity is heavy, the watering frequency should be moderately increased, but in winter it should be reduced to prevent root rot.

If you want the plant to grow healthily and vigorously, fertilizing is an essential task. The cotton rose hibiscus is not demanding when it comes to fertilizer. During the growing period, that is, the flowering season from August to October, it is recommended to apply dilute organic fertilizer 2-3 times per month. For established potted plants, fertilization can be reduced, and in winter, fertilization should also be stopped. As for pruning and shaping, regular pruning is needed to keep it neat and attractive. When pruning, cut off diseased branches, leggy branches, and overly dense branches to prevent excessive branching from affecting the shape.

Finally, regarding precautions, the cotton rose hibiscus is prone to attracting pests, so it is best to keep it on a windowsill with a gauze screen in front; otherwise, it is likely to suffer from green leafhoppers and red spider mites, among other issues. When pests and diseases appear, spraying a 500-800 times diluted solution of zineb can provide relief. If it later becomes severe and the lesions merge into one patch and spread across the entire leaf, pay attention to light exposure and ventilation during treatment.
