Goldenrods are a difficult group to identify, and there are many similar species.  A moderately tall goldenrod in a sunny place with a branching inflorescence is likely this species.  Tall goldenrod (S. altissima) also occurs in open areas.  It is tall, with narrow leaves and an inflorescence made of curved one-sided clusters.
