Is Catharanthus roseus cold-resistant?
The following is an introduction to whether Catharanthus roseus is cold-resistant and the planting content of green plants and flowers that are cold-resistant outdoors for netizens. Next, the editor will answer your questions in detail.
Winter is approaching, and how to survive the winter has become a major issue for plants. If there is heating at home or it is not cold in winter, it is not a big deal to survive the winter. If there is no heating at home and the temperature is low, surviving the winter becomes a top priority. Otherwise, the plants that are lush and full of flowers in autumn will die in winter. There are 20 common plant varieties for winter survival. It is recommended to save them if you don't know how to care for them.
Rose
Roses are relatively cold-resistant and can generally withstand temperatures below -20 degrees Celsius. Some varieties can even tolerate temperatures below -30 degrees Celsius. For safety, it is recommended to keep them in an environment above -15 degrees Celsius. Potted roses have less cold resistance than those planted in the ground. When the temperature drops to about 0 degrees Celsius, it is necessary to stop watering and dry them in advance. Excessively wet soil can reduce their cold resistance and even freeze the pot. For newly planted rose seedlings or very weak seedlings in late autumn, it is best to keep them in an environment above -10 degrees Celsius.
Bougainvillea
Bougainvillea is not cold-resistant. It is best to keep it in an environment above 5 degrees Celsius in winter, so the leaves remain green and it can survive the winter safely. When the temperature is below 5 degrees Celsius, the leaves will gradually turn yellow and fall off. Some frost-sensitive or new/weak seedlings may get frostbite or die when exposed to temperatures below 5 degrees Celsius for extended periods. Strong bougainvillea plants can tolerate temperatures slightly below 0 degrees Celsius, and some varieties can even tolerate temperatures below -5 degrees Celsius. For safety, the winter temperature of bougainvillea should not be lower than 5 degrees and at least not below 0 degrees. When the temperature is below 5 degrees, it should be kept dry and not watered.
Happiness Flower
Happiness Flower prefers a cool growing environment but is not frost-resistant. To make it bloom in winter, it should be kept in an environment above 10 degrees Celsius. When the temperature is below 10 degrees, the leaves will turn red and stop growing. If the temperature is below 5 degrees for an extended period, not controlling watering can cause frostbite or death. When the temperature reaches about 0 degrees Celsius, the happiness flower is highly susceptible to frostbite. It is recommended to keep the minimum temperature for the happiness flower above 5 degrees and at least not below 0 degrees.

Crab Claw Cattleya
To keep Crab Claw Cattleya alive during winter, it should be kept in an environment above 5 degrees Celsius. To make it bloom in winter, it should be kept in an environment above 10 degrees Celsius. At low temperatures, Crab Claw Cattleya stops growing, the leaves turn red, and it doesn't bloom. When the temperature is below 10 degrees, it is necessary to control watering and water less. When the temperature is below 5 degrees, watering should be stopped, and it should be kept in a well-lit and sheltered environment.
Tiger Skin Orchid
Tiger Skin Orchid is not frost-resistant. The critical temperature for surviving winter is 5 degrees Celsius, and it is prone to frostbite or death below 5 degrees. When the temperature is below 15 degrees, the growth rate of Tiger Skin Orchid slows down. Below 10 degrees, it almost stops growing. Therefore, when the temperature is below 10 degrees, it is necessary to control watering and keep it dry. At around 5 degrees, Tiger Skin Orchid should be kept completely dry to improve its cold resistance.
Iron Wire Clematis
Iron Wire Clematis has good cold resistance. Adult plants grown in the ground can tolerate temperatures below -20 degrees Celsius, and those south of Beijing can survive the winter in the open. For Iron Wire Clematis seedlings purchased in late autumn, it is recommended to keep them in an environment above -10 degrees Celsius. Keeping Iron Wire Clematis at an appropriate low temperature in winter is beneficial for blooming the following year. Therefore, for Iron Wire Clematis kept indoors, the temperature should be controlled. If the temperature is above 10 degrees, the new buds will sprout early, affecting the blooming next year.
