You can know the weather by looking at plants.

Born in Xishuangbanna, when the storm comes, there will be a lot of flowers. According to this feature, people can know the weather changes in advance, so it is called "Rain Flower". Rain flower, also known as red rain curtain, calamus lotus and leek, is an herb flower of Allium in Amaryllidaceae. Its leaves are flat and linear, much like the long leaves of leeks, hanging in an arc. Bulbs are round and slightly thicker than onions. Flowers bloom in spring and summer, and the flowers are pink or rose red. China is native to Mexico and Cuba. It likes to grow on fertile, well-drained and slightly sticky soil and is not cold-tolerant.

2. Zoysia japonica

Perennial herbs Zoysia japonica and thatch can also predict the weather. When Zoysia Zoysia appears moldy hairs at the junction of leaves and stems, or when the junction of leaves and stems of thatch bubbles, it means rainy days. Therefore, there is a saying that "Zoysia japonica grows mildew and it will rain"; The proverb "The straw stalks spit, and it will rain tomorrow".

Interestingly, grass can not only predict weather, but also measure temperature. There is a "temperature grass" in southern Sweden, which can measure the temperature like a thermometer. This grass has long oval leaves and blue, yellow and white flowers, so it is also called "pansy". Its leaves are extremely sensitive to temperature. When the temperature is above 20℃, the leaves extend obliquely upward. If the temperature drops to 15℃, the blade will move down slowly until it is parallel to the ground. When the temperature drops to 10℃, the blades extend obliquely downward. If the temperature rises, the blades will return to their original state. Local residents can know the temperature according to the extension direction of its leaves.

4.mimosa

Touch the mimosa with your hand, and its leaves will shrink. If the contraction is slow, or the leaves open immediately after closing, it indicates that it will rain soon. On the other hand, if it is closed soon, but it takes a long time to recover, it indicates a clear sky in Wan Li.

5.moss

As the saying goes, "When the water surface is covered with moss, there will be heavy rain", because before it rains, the temperature drops suddenly and the pressure on the water surface of the pond decreases, resulting in the moss on the bottom of the water surface of the pond.
