Answer

Weed pollens also vary geographically. Many of the weeds, such as short ragweed, which is a common cause of allergic rhinitis in much of the United States, are most prominent in the late summer and fall. Other weed pollens are present year-round, particularly in warmer climates. Common weeds associated with allergic rhinitis include short ragweed, western ragweed, pigweed, sage, mugwort, yellow dock, sheep sorrel, English plantain, lamb's quarters, and Russian thistle.
