What tree is this made of? What's this look called? What's the use ~ ~

Hello, Lagerstroemia indica and Haitang are the main tree species that weave and cultivate this kind of ornamental shape. First make a mold that needs to be woven, such as vase-shaped and gazebo-shaped, and then tie it to the mold regularly and grow for about 2 years. In particular, the vase-like shape is full of flowers at the top of the flower season, which is particularly eye-catching, whether it is planted in a community, park or square. Our base has cultivated this modeling plant in www.jrhmw.com, in parks and squares.
