Winter weather temperature

First of all, plum blossoms are in full bloom in spring!

Winter flowering is called Chimonanthus praecox, and they are not the same species at all.

If this problem is ruled out.

This kind of wintersweet is generally around 0 degrees, which is most suitable for flowering.

Flowers below-10 will freeze, but plants can overwinter at-15.

So you can't see this in the northeast winter when it is easy to break at -20.

When the temperature returns to above 10 degrees, plants begin to grow leaves.

This is probably the feeling that the breeding temperature and the growth temperature are out of sync. Chimonanthus praecox is self-pollinated, the flower is very delicate, and the weak ultraviolet rays in winter will not burn its flowers (key point)

At the same time, its seeds mature for a long time, so that after the leaves grow out in spring, its nutrition can fully supply its own seeds and baby development.

In addition, we say that it is warm winter, but the time of entering spring has not changed much, so the role of wintersweet is not great.
