Goldenrod

Goldenrod
(Solidago canadensis)

This is a native plant, but has become a nuisance in meadows and along roadsides. The plant may be somewhat toxic to livestock, and the pollen is believed to cause allergies in many people.

It spreads by creeping roots (rhizomes) and also by seeds, and is therefore very difficult to control.

The bright yellow flowers are very small, but numerous. They commonly occur along just one side of an arched stem.

The flower heads have tiny ray flowers and also disk flowers.
