Giant goldenrod

Description:

Solidago gigantea is an herb up to 200 cm tall, sometimes spreading by means of underground rhizomes. They often grow in clumps, with no leaves as the base but numerous leaves on the stem. At the top, each stem produces a sizable array of many small flower heads, sometimes several hundred. Each head is yellow, containing both disc florets and ray florets.

Habitat:

Habitats include openings in floodplain woodlands, borders of woodlands, low partially shaded areas along rivers and ponds, riverbottom prairies, wet prairies, prairie swales, soggy thickets, fens, and ditches. The preceding list includes both sandy and non-sandy habitats. In general, giant goldenrod is an adaptable plant with low fidelity to any particular habitat. Its main requirement is the availability of adequate moisture.
