Goldenrod - Solidago

Goldenrod is a genus of about 100 to 120 species of flowering plants in the aster family, Asteraceae. Most are herbaceous perennial species found in open areas such as meadows, prairies, and savannas. There are about 20 species of Goldenrods known to grow in Wisconsin (8-10 of them are fairly common). This plant is often wrongly blamed for August hayfever.

Canada Goldenrod (Solidago canadensis), is the most abundant species in Wisconsin.

Other names for (Solidago canadensis): Canadian goldenrod, common goldenrod

Goldenrod
by Scottish author, Elizabeth Gordon

Golden-Rod, the lucky chappy,

Grew up strong and tall and happy.

Slept out doors, if you'll remember,

All those cold nights in September.

Above: At first one might think this is a species of Goldenrod because of the branches stemming around a rosette. However, this is called a flower gall, rosette gall or bunch gall. It is formed when a gall fly lays an egg in a leaf bud. When the egg hatches, the grub somehow keeps the stem from growing; but, does not seem to hurt the plant or prevent it from flowering.
