Is crape myrtle ticklish?

We say that this tree is ticklish, but it is actually its foundation that makes this flower its present name. The wood of Lagerstroemia indica is relatively hard. The biggest feature is that the roots and tops of branches are roughly the same thickness, and the upper part is heavier than ordinary trees, which determines that it is easy to shake. When we scrape the branches with our fingers, the vibration caused by friction is easily transmitted to more parts of the branches through hard wood, so it is easy to cause vibration. In fact, no tree is really ticklish. Tree phloem has no sensory cells like animal skin. Imagine the tremor of crape myrtle as ticklish.

There is also a good explanation for its ticklish condition. That is to say, the branches of Lagerstroemia indica are about the same thickness as the top part of the root. Compared with those trees and shrubs that are obviously thicker on the top and thicker on the bottom, Lagerstroemia indica is more top-heavy. When scratching its branches gently, the vibration generated by friction is easily transmitted to the top branches and flowers through the hard branches, causing shaking, which will gradually accumulate and increase in amplitude.

So when we block the sun, or touch the sun a little. It will slowly close the bud, like a shy child. However, in order to better contrast the meaning and interest of Wei Zihua, we nicknamed it "itch tree", and the survival rate of this Wei Zihua tree is also very high. In practice, there is not much difficulty. To put it bluntly, as long as you want to raise it, it can be raised anyway.

This is not nonsense, there are some facts. Flower experts have done such experiments. They are worried that Lagerstroemia indica can't feed without sowing. But after the actual practice, such worries are superfluous. Even though there is still a big unknown about Lagerstroemia indica, I believe that one day scientists will reveal the real reason why Lagerstroemia indica is "ticklish".
