Solidago Canadensis.

It grows on waste ground and alongside paths, railway sidings and river banks. These pictures were taken at the RSPB Fairburn Ings reserve alongside the children's play area, though it can be found around the country. It flowers between July and September. It was introduced to the English gardens in the 1640s, first shown to be naturalised in the wild in the 1880s and was common in the wild by the 1930s. Canadian Goldenrod is a vigorous, perennial, herb and can reach heights of around 2 metres. The flower heads are bright yellow with tiny crowned heads. The leaves are long and oval shaped.
