(Anise Scented Goldenrod, Licorice Goldenrod)
Asteraceae (Composite Sunflower) Family
The base of the small flower is broader than the tip. Each floret is symmetrical in form. Disc flowers are bisexual and yellow. Ray flowers are female and yellow. Flowering occurs in late summer to early autumn.
The related S. tortifolia is similar to Sweet Goldenrod but the plant has elongate rhizomes. Its leaves are not scented and most are finely serrate. Since both plants inhabit similar places, distinguishing one from the other may be difficult except for the sweet anise-like scent of S. odora.
