In China, the trend of plant invasion is becoming more and more serious, such as the American Shanglu (vertical Shanglu), the Canadian goldenrod, the Feipeng grass, the horse cherry (five-color flower) and so on.

The flowering and fruiting period is from September to November, and the flowers are yellow, head-like inflorescences, arranged in a narrow and long conical shape, and look a bit like spikes from a distance. At present, this plant is distributed in most provinces of China, and is commonly found on hillsides and roadsides.
