What plants are like mimosa?

As long as people or animals come near, they will roll their leaves, and there are chestnut trees that are very sensitive and can predict the weather.

Mimosa pudica

Mimosa It is a perennial herb or subshrub of Leguminosae. Because its leaves will respond to heat and light, and will immediately close when subjected to external force, it is named mimosa. Shaped like a fluff ball. After flowering, it bears pods and the fruit is oblate. The leaves are feather-like compound leaves, alternating with each other and arranged in a palm shape. Flowering after midsummer, with oblong flower heads and 2-3 flowers in leaf axils. The flowers are white and pink, with bell-shaped calyx, 8 tiny calyx teeth, 4 petals and 4 stamens, and the ovary is hairless. The pods are flat, each pod node 1 grain, and fall off at maturity. Flowers bloom in September. ?

The flowers, leaves and pods of mimosa have a good ornamental effect and are easy to survive, so it is suitable for potted plants on balconies and indoors (people who eat mimosa or contact it too much can also cause hair loss). It can also be planted in yards and other places. Mimosa is different from ordinary plants. When it is touched, the petiole droops and the lobules close, so people understand it as "shy grass", so it is called grass-sensitive, grass-drinking, grass-shy, grass-ashamed and grass-ugly (Cantonese). Native to tropical South America, it likes to be warm and humid, and has general requirements for soil.

Scratch a tree?

Glycyrrhiza uralensis Fisch, alias Lagerstroemia microphylla, Lagerstroemia tenuifolia, Melaleuca, Full House Red and Milky Crystal. It is a dicotyledonous plant of Lagerstroemia of Lysimachiaceae. Of southern Asia and northern Australia. It is distributed in East China, Central China, South China and Southwest China, and widely cultivated in various places. Lagerstroemia indica has beautiful posture, smooth trunk and bright colors; It happens to be summer and autumn when flowers bloom, and the flowering period is particularly long, from June to September. Therefore, it is known as "Hundred Days Red" and "Summer Blue and White Flowers Full". It is a good bonsai for ornamental flowers, stems and roots. Wei Zi is also the city flower of Jincheng.

Botanists have concluded that, similar to mimosa, the leaf rolling phenomenon of prurigo is based on the reaction of electric pulses. The electrical signal in the instrument can pass through the "skin cells" of prurigo and along the pipeline of wooden parts, and the stimulated electrical signal is very similar to that of animals. It is not difficult to see that this plant has a complex nervous system.

Chestnut tree?

Chestnut tree, deciduous tree, the fruit is called chestnut, and the nuts are sweet and edible. Wood is solid and can be used in buildings and utensils, and bark can be used for tanning and dyeing. Chestnut trees are used in gardens. Chestnut trees are planted as excellent landscape trees in landscaping around the world, and are usually transplanted with half-crown width.

Location: Shandong, Anhui, Jiangsu, Hebei, Henan and other places. Chestnut, peach, apricot, plum and jujube are also called "five fruits".

Chestnut trees are not only sensitive, but also can predict the weather. After winter, when it is predicted that snow or frost will come, it will germinate several weeks in advance. Studies have confirmed that chestnut trees can predict the arrival of severe winter by measuring the length of night time.

French biologists chose a newly unearthed seedling with two tender leaves as the experimental object. They gently pricked one of the leaves with a needle a few times, but missed it, and then continued watering to let the seedlings grow. In this way, the side of the leaf that is not tied grows normally, while the growth rate of the tied side slows down obviously. It seems that plants have remembered the danger hidden on the pricked side. After many experiments, biologists have noticed that the memory of plants can last about 13 days.
