Description
A description of Helianthus strumosus is provided in The Flora of North America.
Helianthus strumosus is a perennial herbaceous species. It is colonial, with perennating rhizomes. This species also tends to be a taller species, with stems up to two meters long[1].

Ecology
Habitat
H. strumosus occurs in drier, well-drained uplands, including sandy ridges, shaly slopes of oak-pine woods, crests of limestone bluffs, prairie over chalk, pine woodlands, and rocky embankments[1]. It also seems to prefer higher light conditions, occurring in clearings and edges of woodlands, and other open, sunny locations. In addition to more rocky soils, it can be found in sandy silt, sandy clay, or sandy loam. This species also occurs in disturbed habitat, including roadsides, power line corridors, and semi-cleared woodlands. Associated species include Longeleaf pine and Oak species[1].
Phenology
Flowering has been observed in June, July, August, September, and November. Fruiting has been observed in July and August[1].
Fire ecology
