When does Sophora japonica (a cold-resistant ornamental flower tree in the northern courtyard) bloom?

It is spring again. Every April, the most coveted thing is not the Toona sinensis on the tree, nor the shepherd's purse in the field, but the sweet locust often planted on the side of the house and the roadside. Widely cultivated in most parts of China, but mainly in the north, mainly distributed in the Loess Plateau and the North China Plain, generally flowering in April and May every year. The flowering period is average.

I am from Dalian, and the Sophora japonica in Dalian has also been rated as the city flower. At this time of year, Sophora japonica is fragrant and fragrant, which is really fascinating. Moreover, northerners have a habit of Sophora japonica, and there is a saying that "planting Sophora japonica in front of the door naturally makes money". It can not only bring the breath of spring, but also bring wealth to the family. Why not? Now at the end of March and the beginning of April, Sophora japonica will begin to mature on a large scale. Many people have long wanted to climb trees and pick them.

In the past, Sophora japonica was only white, but now it's different. I found many purple locust trees by the roadside. I remember when I was a child, I ate the cake of Sophora japonica made by my mother, all of which were white Sophora japonica. So is this purple locust edible? I believe many people don't know that although it is also Sophora japonica, there is a big difference between purple and white. I don't understand. Be careful to eat "poisoning".

The first type: different varieties.

White Sophora japonica is a native variety of Sophora japonica, which not only smells fragrant, but also tastes sweet. However, the purple Sophora japonica is a new variety cultivated artificially, and its main function is to be used as an ornamental in greening, so its value is mainly used for ornamental, not edible.

The second type: the aroma is different.

As we all know, Sophora japonica has a strong fragrance, which is all over the mountain. However, just pick a purple locust and put it under your nose to smell it. There is basically no fragrance.

The third type: different uses.

White Sophora japonica can be eaten, while purple Sophora japonica is generally used for viewing and is not recommended.

The fourth type: different nutrients.

Sophora japonica is rich in nutrients and various nutrients necessary for human body, so it can be made into various delicious foods. However, Amorpha fruticosa has basically no nutrition and is not recommended to eat.

Many people say that Sophora japonica is poisonous. Here, I'll give you a lecture on popular science. Whether it is Sophora japonica or Sophora japonica, there is a component that can be decomposed into photosensitive substances in the human body. Exposed face, hands, feet and other parts of the human body are exposed to direct sunlight.

It may lead to metabolic disorder and induce "solar dermatitis", and the content of this component in Sophora japonica is higher than that in Sophora japonica, so people with sensitive skin will be allergic soon after eating Sophora japonica. Everyone should pay attention to these reasons, and everyone should use Sophora japonica. There is no need to eat Amorpha fruticosa, which has no fragrance and is not delicious.

The above is today's sharing. Have you learned something about Sophora japonica? I wonder if the purple locust can be eaten this time? These two kinds of Sophora japonica are very different, so don't be confused in the future.
