Riddell's Goldenrod is a rare plant to find in Missouri, but it is pretty easy to grow and needs to be used more often in native plantings. It is one of the few "flat-topped" goldenrods: the inflorescence has a more horizontal presentation than the other goldenrods. Other flat-topped goldenrods include rigid goldenrod, which likes drier soils, and white upland aster, which has white flowers & also prefers well-drained environments.

While it is normally found growing in high-quality wet-soil habitats, it can certainly survive some neglect in the home landscape. 

Goldenrods, with their showy, prominent, yellow flowers, are typically blooming at the same time as the various ragweeds. Ragweed flowers are less flashy but produce the allergy-inducing pollen that goldenrods get blamed for.
