Canada Goldenrod is native to North America and it is a member of the Asteraceae family. This species makes a bold statement in the late summer garden. Although it and other Goldenrods are commonly blamed for hay fever, this discomfort is usually caused by pollen from Common Ragweed (Ambrosia artemisiifolia), which are less conspicuous plants with greenish flowers that bloom at the same time.
Goldenrod is found naturally on abandoned farmlands, infrequently grazed pastures, and tall grass prairies, also along roadsides and fence lines, in dry open fields, and in open woods or damp meadows that dry out every year. It tolerates a wide range of soil fertility and texture conditions, but is typically found in fairly moist soils. Goldenrod is not found on waterlogged sites and only rarely on very dry sites. Goldenrod is fairly shade intolerant although it occurs in sparsely wooded areas and is sometimes dominant or co-dominant in disturbed forest understories.
In your home garden it provides good color and contrast in your fall perennial border, wild garden, meadow or naturalized area. It can grow to 4 feet and can be paired with garden phlox, Echinacea, New England asters and Black-eyed Susan.
Parts of the plant are used for medicinal purposes. The root can be made into a poultice for burns. Flowers made into a tea for fevers, crushed flowers can be chewed for sore throats. A tea can also be used in treatment of lower urinary tract inflammatory diseases.
