Can goldenrod cause allergic reaction?
Technically speaking, any plant can cause allergy but goldenrod is not known as a plant that commonly triggers allergy symptoms. It happens to bloom at the same time as ragweed, a well-known allergen. Since pollen travels on the wind, it is difficult to pin down the culprit without testing. If you react allergically to ragweed, daisies and marigolds, you might also react to goldenrod as it is in the same family of plants. (WebMD)
