① Lagerstroemia speciosa belongs to Dryopteridaceae, commonly known as "ticklish tree". It is a unique tree species among trees, also known as mosaic tree, also known as skinless tree, full house red and hundred days red. Because of the special flowering period, it blooms continuously from July to 10, hence the name Hundred Days Red.

Yang Wanli, a poet in the Song Dynasty, praised: "It is better to be infatuated with beauty than to be exposed to the wind. Who said that flowers will not be red for a hundred days, and crape myrtle will bloom for half a year. " Xue Hui in the Ming Dynasty also wrote: "Lagerstroemia indica blooms for the longest time, rotting for ten days, and continues to open new flowers in summer."

(3) When Lagerstroemia indica grows up, the trunk epidermis falls off and is smooth and skinless. If people gently touch it, it will immediately shake its leaves, tremble all over, and even make a weak "giggle" sound. This is a systemic reaction of its "itch", which is really amazing.

④ There are four varieties in Wei Zi, including Chiwei, Yin Wei and Cuiwei. The best is the delicate blue petals, which is a panicle with the top of a new branch 20 cm long. Each flower has six petals, and the petals are wrinkled like roulette. Flowers are full of trees, so it is also called full house. The result is a capsule, which looks like.

Lagerstroemia indica originated in China, distributed in the Yangtze River valley, and also cultivated in South China, Northwest China and North China, with strong adaptability.

⑥ Lagerstroemia indica is drought-tolerant, waterlogging-tolerant, moist, light-loving and fat-loving. It has strong resistance to sulfur dioxide, hydrogen fluoride and nitrogen, and can inhale harmful gases. The dry leaves can absorb 65,438+00g of sulfur per kilogram, and grow well. It can also absorb dust. In the cement plant, 200-250 meters away from the pollution source, leaves can absorb 4042 grams of dust per square meter.

⑦ Ziwei also has medicinal effects. Li Shizhen discussed in Compendium of Materia Medica that its bark, wood and flowers have the functions of promoting blood circulation, dredging meridians, relieving pain, reducing swelling and detoxifying. Seeds can be used as pesticides to drive away pests. Leaves can cure white dysentery, flowers can cure postpartum hemorrhage, children's rotten head and fetal poison, and radically cure carbuncle, swelling and sore poison, which can be described as treasure all over.
