Misc.: S. altissima看is part of the看Solidago canadensis看species complex. S. altissima看has sometimes been classified as a variety of看S. canadensis.

In distinguishing between the two, note that S. altissima is remotely toothed; S. canadensis is sharply toothed. Also,the leaves of S. altissima are scabrous (rough to the touch) on the surface, and somewhat downy beneath. S. canadensis is not. Both S. altissima and S. canadensis are largely lacking in basal leaves.

altissima看= very tall

Tall goldenrood is food for many types of bees, wasps, butterflies, moths, beetles, and other insect species.看Praying mantises often lay their eggs on goldenrod. It tends to grow in colonies and the stands provide cover for birds and small mammals.

Tall goldenrod was used medicinally by Native Americans to relieve cramps, as well as as a dye for wool, silk, and other fabrics.

Tall goldenrod is often mistakenely blamed for causing hay fever because it blooms at the same time as the real culprit, ragweed.看

Witmer Stone, 1910, notes that S. altissima is often found growing with Gnaphalium obtusifolium.
