What determines the purple color of osmanthus?

Lagerstroemia speciosa, commonly known as "ticklish tree", is a strange tree species among trees. Lagerstroemia indica is a mosaic tree, also known as skinless tree, full house red and hundred days red. Due to the special flowering period, it blooms continuously from July to 10, hence the name Hundred Days Red. Northerners call crape myrtle "monkey thorn", which means the tree is too slippery for monkeys to climb.

Its beauty lies in its lack of bark. Few of the thousands of trees in Qian Qian in the world are skinless, and things are rare. The trunk of young Lagerstroemia indica has an annual epidermis and falls off by itself every year. The trunk looks fresh and smooth after the epidermis falls off. Old Lagerstroemia indica, the tree body does not revive the epidermis, and the tendons are quite exposed. Bright and smooth.

When Lagerstroemia indica grows up, the trunk epidermis falls off and is smooth and skinless. If people touch it gently, they will immediately shake the leaves, tremble all over, and even make a weak "giggle" sound. This is a whole-body reaction of its "tickling", which is really amazing. Lagerstroemia indica * * *, there are four kinds of red, silver and emerald, among which blue petals are the best.
