Canadian Goldenrod – Solidago canadensis

The golden-yellow flower heads are on numerous horizontal branches which decrease in size up the stem. The leaves are many and lance-shaped with toothed margins. This is a tall plant which can grow up to 2 m height.

It flowers August to October, and is found naturalised on roadsides, railway embankments, wasteland and field margins. Originally native to North America, it has become fairly common throughout England, lesser so elsewhere.
