This scanning electron microscopic (SEM) image reveals some of the ultrastructural details of the perennial goldenrod flower, Solidago canadensis, also known as Canadian goldenrod. Goldenrod is often blamed for causing hay fever, for it blooms in late summer, however, its pollen is too heavy and sticky to be blown far and wide, and it's usually ragweed, Ambrosia spp. that are the culprits.
