Rough-leaved Goldenrod doesn't have a lot of flowers. They tend to be scattered along the stem, sometimes with a raceme at the end of the stalk.

Note that the flowers are somewhat large for Goldenrod, and the clusters don't have a lot of flowers in them.

As with other Goldenrods, the flowers bloom from the end of the stem down.

The lower stem leaves are very large, and clasp the stem.

Leaves higher up the stem are a lot smaller.

The stem. It is NOT square, like the books say, but rather it is ridged.

The ridges are obvious in the winter remnants.
