Lagerstroemia indica is called an itchy tree?

Ziwei's alias is "itch tree". This is because people find Ziwei as "ticklish" as people. With a slight scratch, the flower will tremble, hence the name. After careful observation and experiments, some botanists found that Wei Zi's "ticklish" phenomenon was actually related to the tree shape of Wei Zi.

Because the trunk of Lagerstroemia indica is obviously different from other tree species, that is, the thickness of the root and the top of the trunk is almost the same. Compared with other tree species, Ziwei is more top-heavy. When we gently scratch its branches, the vibration caused by friction is easily transmitted to the top branches and flowers through the hard branches, causing shaking.

Moreover, this kind of shaking will gradually accumulate, and the amplitude will be bigger and bigger, and the phenomenon of "tickling" that we usually see in Wei Zi will appear.

Extended data:

Osmanthus fragrans, also known as full house, has red and purple flowers and is widely planted as ornamental flowers. Osmanthus fragrans is widely distributed in East China, Central China, South China and Southwest China, and can be widely cultivated everywhere. Osmanthus fragrans can also be kept at home.

Osmanthus fragrans likes sunshine, so it doesn't need to be outdoors in the growing season, so it needs to strengthen the light. Cultivation needs to choose the leeward and sunny place with deep soil layer, fertile soil and good drainage. Although osmanthus is drought-tolerant, it should be watered in time. Pot soil should be kept moist in spring and winter, watered once every morning and evening in summer and autumn, and the watering times can be appropriately increased every day in case of drought and high temperature.

Osmanthus fragrans likes fertilizer and needs to be fertilized regularly. If it lacks fertilizer, it will lead to weak branches and yellow leaves, and the growth of the whole plant will be weakened, with few flowers or even no flowers. Of course, if too much fertilizer is applied, it will easily lead to too many branches and leaves.
