description Goldenrod Overview
Goldenrod is the common name for flowering plants in the genus Solidago, a group in the aster family. These mostly herbaceous perennials produce yellow flower heads, often in branching clusters, and many species bloom from late summer into autumn. Goldenrods are important nectar and pollen sources for insects and are widely used in native-plant gardens, meadows, and restoration projects. Solidago canadensis and related species are widespread in North America.
help Goldenrod FAQ
What kind of plant is goldenrod?
Goldenrod is the common name for plants in the genus Solidago in the aster family. Most garden and wild species are herbaceous perennials with branching clusters of yellow flower heads.
Does goldenrod cause autumn hay fever?
Goldenrod is often blamed because it blooms at the same time as ragweed, but goldenrod pollen is heavy and usually carried by insects. Ragweed pollen is windborne and is a much more common cause of seasonal hay fever.
When does goldenrod bloom?
Many Solidago species bloom from late summer into autumn, when fewer native flowers remain. Their yellow flowers provide late-season nectar and pollen for bees, butterflies, soldier beetles, and other insects.
Which goldenrod species are commonly seen in gardens and fields?
Examples include Canada goldenrod, Solidago canadensis, and wrinkleleaf goldenrod, Solidago rugosa. Species differ in height and spreading habit, so a compact cultivar may suit a garden better than a vigorous field species.
