C. tomentosa is a perennial forb/herb that is a member of the Asteraceae family. Leaf shape varies from elliptic to obovate with denticulate margins. The fruit type an achene (small, dry, and one-seeded). The flower is white with pinkish back petals.
Chaptalia tomentosa is a facultative wetland species commonly found in seepage areas, edges of ditches, along streams, in low meadows, roadside wetlands, open bogs, and swampy woodlands. This species can occur in non-wetland areas such as sandhill seeps, savannas, and pine flatwoods.
C. tomentosa grows in soil types ranging from sandy peat to moist or wet loamy sand. One study found the species to increase in frequency when the overstory is thinned rather than clear cut.C. tomentosa decreased in occurrence or was unaffected in response to soil disturbance by roller chopping in South Florida. It either resisted regrowth or remained unaffected in reestablished native habitat that was disturbed by roller chopping. It increased in frequency in response to soil disturbance by clearcutting and chopping in North Florida flatwoods forests. It also showed positive regrowth in reestablished native flatwoods that were disturbed by clearcutting and chopping.
Chaptalia tomentosa is frequent and abundant in the Upper and Lower Panhandle Savannas community type and is an indicator species for the Lower Panhandle Savannas community type as described in Carr et al. (2010).
Associated species include Pinus elliottii, Pinus palustris, Aristida sp., Serenoa repens, Hypericum fasciculatum, Sarracenia sp., Helenium vernale, Andropogon sp., Ascyrum tetrapetalum, Drosera brevifolia, Xyris sp., Taxodium sp., Sisyrinchium sp., Calopogon sp., Viola lanceolate, and Pinguicula sp.
C. tomentosa has been observed flowering from January to June with peak inflorescence in March.
The species could be hypothesized to be fire-tolerant since it is found in upper Florida panhandle savannas that are fire-dependent. One study found C. tomentosa to significantly increase in frequency in response to a recent fire. As number of growing seasons since past fire disturbance increases, one study found C. tomentosa to decrease in ground cover and frequency over the years.
Herbivory and toxicology
It is considered to have poor forage value.
