Common ragweed

Springdale farm, Oakdale Twp., Noble Co., Okla.

Common ragweed (Ambrosia artemisiifolia) is one of the nasty culprits that causes the hayfever allergy. It is estimated the plant and its larger cousin, the Giant ragweed (Ambrosia trifida), are responsible for 90% of pollen related allergies.
