Along with many flowering ragweeds, you many colorful weeds carrying yellow flowers; these are golden rods; they are not associated with inducing allergy symptoms in fall season.
Golden rods are producing attractive flowers now in many deserted areas across the land. They add a nice color to panoramic view. Goldenrod can grow to height between about three to five feet. They carry bright yellow flowers and slender stems. The leaves are linear with serrated edges.
Allergy tests are done for goldenrod as they are associated with symptoms of allergy. However, the pollen from goldenrod is not often air-borne as the pollen is heavy and sticky and is rarely carried through the air. Even though airway hypersensitive reactions are rare, allergic reaction can develop as a result of direct contact resulting in skin rashes, known as contact dermatitis.
