Helianthus strumosus is a perennial herbaceous species. It is colonial, with perennating rhizomes (FSU Herbarium). This species also tends to be a taller species, with stems up to two meters long (FSU Herbarium).
Distribution
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 (FSU Herbarium). It also seems to prefer higher light conditions, occurring in clearings and edges of woodlands, and other open, sunny locations (FSU Herbarium). In addition to more rocky soils, it can be found in sandy silt, sandy clay, or sandy loam (FSU Herbarium).
This species also occurs in disturbed habitat, including roadsides, power line corridors, and semi-cleared woodlands (FSU Herbarium).
