Solidago canadensis (known as Canada golden-rod or Canadian goldenrod) is an herbaceous perennial plant of the family Asteraceae native to northeastern North America but established as an invasive plant in many other regions. It is often grown as an ornamental in flower gardens

The plant is erect, often forming colonies. Flowers are small yellow heads held above the foliage on a branching inflorescence. In many parts of Europe, Japan and China, it is established as an invasive weed.

In eastern and southeastern China, particularly the provinces of Zhejiang, Jiangsu, Jiangxi and Shanghai, its invasion has reached pandemic levels and has caused widespread concern. It has been reported that the invasion of the Canada Golden-rod along with other invasive plants, has caused the extinction of 30 native plants in Shanghai. In the city of Ningbo, Zhejiang, it has reduced local orange harvests. It is still spreading across China, and sightings have been reported in as far as Yunnan province. Various national and provincial authorities have been on high alert.

In Fukushima it has taken over the rice fields that have been temporarily abandoned because of the nuclear power plant disaster.
