1、 Cause

1. Mimosa is different from other plants. There are leaf pillows at the bottom and petiole of its leaves, and the distribution of parenchyma cells of leaf pillows is also different. After people touch it, there will be a pressure imbalance, and the cell fluid in the lower part will increase, which will close the leaves tightly and look like shyness

2. It is native to South America, where strong winds and heavy rain are often encountered. When rain falls on its leaves, the petiole will begin to sag and the leaves will close. In fact, this is to avoid its own harm, which can be said to be self-protection

2、 Precautions

Don't always touch its leaves during maintenance, because it will close tightly after touching the leaves. Finally, it will take about 5-10 minutes to recover. If you keep touching it, the parenchyma cells in the leaf pillow will be lost and may not be supplemented in a short time. If you touch it again, you won't be shy and feel as if there are some wilting
