Notes This is a very common plant in the late summer and fall. While many people think that their fall allergies (hay fever) are caused by goldenrod, it’s pollen is too heavy to be airborne so the allergies are caused by ragweed which pollinates at the same time. Stems are often invaded by insect larvae (usually a solitary wasp or fly larvae) causing a large swelling called galls.
