Why is crape myrtle called prurigo? Where does it itch?

The prurigo tree has no specific itchy part, but scratching its branches will cause other branches to vibrate, so it is called the prurigo tree.

The wood of Lagerstroemia indica is hard, the biggest feature is that the roots and tips of branches are almost as thick, which is different from the characteristics of thick under the trunk, that is to say, the upper part of Lagerstroemia indica is heavier than ordinary trees, which determines that it is easy to shake.

When people scratch its branches with their fingers, the vibration caused by friction is easily transmitted to more parts of the branches through hard wood, so it is easy to cause more branches to swing, so it is called an itchy tree.

Lagerstroemia indica has strong vitality, is easy to plant and cultivate, and has low requirements on soil, but it grows best when planted in deep and fertile sandy loam. Sex likes light, so it should be planted in the lee of the sun or under the roots of the south wall of the courtyard. If the light is insufficient, plants will not only spend less or not, but even grow weak and have small branches and leaves.
