What plants can forecast the weather?

1. Feng Yuhua

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".

3. Gay men

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.

6.willow leaves

When walking by the river in summer, if you find that the willow leaves have turned white, it may rain in the future. Because the willow leaves will all reverse before it rains, and the reverse side of the willow leaves is light green with a layer of "white frost" on the surface.

7.pumpkin vine

In summer morning, the top of pumpkin vine is generally upward, which indicates that the weather will turn from sunny to rainy. Because the stalk at the top of the pumpkin vine usually grows downwards and forwards. However, if the top of pumpkin vines is generally facing down on rainy days, it indicates that the weather will clear up.

8. Artemisia scoparia

Artemisia scoparia is a plant with strong drought tolerance. In the dry weather where it doesn't rain for a long time, if there are many tender white buds on the roots of Artemisia selengensis, it indicates that it will rain soon.
