What is wisteria tree, also known as tung flower?

Wisteria, also known as wisteria and rattan, is an excellent ornamental vine. Li Bai once wrote a poem: "Wisteria hangs a cloud tree, Hua Teng is suitable for spring, and the dense leaves hide the beauty of birds." Vividly depicts the graceful figure and charming style of wisteria. In late spring, it was the time for wisteria to bloom, but I saw a string of huge spikes hanging from the branches, with blue purple and rosy clouds around. Gray-brown branches and vines meander like dragons and snakes.
