Its flowers are green and are [[pollinated]] by wind rather than by insects, and the pollen is one of the main causes of late summer [[hay fever]]. Flowers are borne from midsummer through early fall.<br /> <br /> The plant is erect, growing to 3 meters tall from clumping rootstocks.<br /> <br /> [[Category:Asteraceae]]</div>
