Other flowers hibernate in winter. Why can wintersweet be cold-resistant?

Plum buds need low temperature, even in summer, which is the same as in winter, except that her flowers are white and bigger than those in winter, so she blooms in severe winter.

Because she blooms in winter, she is called wintersweet.

Plum blossoms not only bloom in winter, but also need different temperatures to grow leaves, so some plants bloom first, and some plants have the same growth temperature requirements for flower buds and leaf buds, so there will be flowers and leaves at the same time, and some plants will grow leaves first and then bloom, and all kinds of plants will bloom.

When Chimonanthus praecox blooms, it usually snows, so I want to enjoy Chimonanthus praecox. After the snow, you will walk through the snow, so it is also called Xue Mei. It is also called winter plum because wintersweet blooms in early winter and bears fruit in late winter, which is accompanied by winter. Chimonanthus praecox likes sunshine, but also endures semi-shade. Afraid of wind and cold, it can safely overwinter when the temperature is not lower than-15℃. It can be cultivated in the open field in the south of Beijing, and the flowers will be frozen when the flowering period meets the low temperature of-10℃. Originally from China, it likes warm climate and is cold-resistant, but generally it can't resist the low temperature below-15c-20c. It is very sensitive to temperature. It blooms when the average temperature reaches 6c ~ 7c within ten days, especially after the first warming. The air humidity in Meixi is relatively high, but good drainage is needed to avoid heavy rain during flowering. After several days of waterlogging, a large number of yellow leaves or root rot may die. The requirements for soil are not strict, clay loam or loam is the best, neutral to slightly acidic is the most suitable, and slightly alkaline can grow normally. Avoid planting in the tuyere. Plum is a positive tree species, and it is best to plant it in a sunny and well-ventilated place. Otherwise, the growth will be poor, and there will be few or no flowers at all. Strong hair skills, so it is more resistant to pruning, and old trees are easy to rejuvenate.
