#How beautiful are the wildflowers on the roadside#This flower is a catalpa tree, not very beautiful, but it is definitely a wildflower, and it is a flower with a long history. The flowers of one of the few ancient fossil tree species that can be traced back to the geological time of the Quaternary glaciation and have been preserved through the changes of China's prehistoric geological and geomorphological structure.

Catalpa, also known as catalpa tree and wood king, is an alpa tree in the crape myrtleaceae family. In ancient times, the name of the catalpa tree was called differently in the history books of the past dynasties, with the Spring and Autumn "Book of Poetry" calling it "chair", the biography of Weizuo recording the catalpa tree as "Hagi", the Warring States "Mencius" calling the catalpa tree "Jia", and the Western Han Dynasty History Records originally called "揪".

The trunk of the catalpa tree is straight and the wood is hard, making it a good building material. The catalpa flowers have 2 to 12 flowers, the sepals are spherical when the buds are rounded, the 2 lips are lobed, the corolla is light red, the inner surface has 2 yellow stripes and purple spots, and the catalpa flowers can be fried and eaten.
