Appearance

The plant is called the "zigzag goldenrod" because the thin, wiry stem zigs and zags back and forth, changing direction at each node . The plant bears sometimes as many as 250 small yellow flower heads, some at the end of the stem, others in the axils of the leaves. The leaves are very broad, almost round, but with an elongated tip at the end and large teeth along the edges.

Habitat

It grows in a variety of habitats including mesic upland forests, well drained floodplain forests, seepage swamp hummocks, and rocky woodlands.
