Although it becomes warm in the daytime, it becomes cold suddenly from evening.
The contention of winter and spring continues at this time.
At my home, a Goat Willow begins activity first of all.

A thing like a brown bud comes out at first, and then a cotton hat appears from under the brown bud.
Although it is thought that the core (?) of a cotton hat is usually gray,
the goat willow of my house is pink.
I don't know whether this is a crossbreed or not.
Anyway, the goat willow in my house is pink.
At first, the whole is pink, then it changes to gray from the under of the core.
