Goldenrods are notoriously difficult to identify to a particular species, so make sure you don't rely on a single source for your identification information. This could easily have been listed as Solidago canadensis as it so very closely resembles it & some authorities list Solidago altissima as a variety of S. canadensis. The USDA Plants Database lists S. altissima as a separate species. According to the Audubon eastern wildflowers book it is a separate species as well as having it blooming into the month of November.
The inflorescence of the yellow Solidago altissima is at the top of a stem which is generally a single stem.
The flower clusters are directed more or less to one side of the stem of the inflorescence. Each blossom normally has 5-7 disk flowers as well as 9-17 ray flowers.
One identifier which is key in identifying different species of goldenrod is the structure of the veins in the leaves. S. altissima has 3 main veins; a characteristic shared by S. canadensis & C. gigantea.
This grows in a wide range of soil types as well as moist to dry areas. The height of the plant is largely determined by the moisture content as well as the fertility of the soil.
Native Distribution: Most of s. Canada & AK, s. to VA, LA & CA
Native Habitat: Dry to moist roadsides, thickets, prairies & open woods.

This is one of the most common species of Goldenrod. It is in the category of the goldenrods with the plume-like, graceful flower clusters and with sharp pointed long, narrow leaves with parallel veins. The leaves are usually just slightly toothed. As the name of both common and scientific names say, it is the tallest species often 6 to 7 feet high or more. It is native from southern Ontario & Quebec to New England down to central Florida to many areas of New Mexico up to spots in Montana in fields, meadows, along roadsides & shores & railroad tracks, and woodland edges.

Flower heads arranged in a pyramidal cluster. Native wildflower in the midwest liking disturbed soil in prairies, fields, pastures, and roadsides. Wrongly blamed for allergies (offender is ragweed). Can form large colonies.
