PhenologyFlowering and fruiting August-October.
IdentificationZigzag Goldenrod is distinctive in its somewhat zigzag stem and basal and lower stem leaves ovate, sharply toothed, taper-pointed, and wing-stemmed. The inflorescence is composed of several heads each in middle to upper leaf axils, plus a terminal spike. Appalachian Goldenrod (S. flaccidifolia) is similar but has somewhat narrower leaves and the stem is straight, not angled slightly at each node as is Zigzag Goldenrod. This is quite a striking plant owing to its zigzag stem and large rounded leaves, but it isn't a species seen routinely in the mountains.
