|Natural range of Pseudognaphalium obtusifolium from USDA NRCS Plants Database.|
Common names: rabbit tobacco or sweet everlasting(Nelson 2005), eastern rabbit-tobacco, fragrant rabbit-tobacco
Synonyms: Gnaphalium obtusifolium Linnaeus; Gnaphalium obtusifolium var. obtusifolium
Varieties: Gnaphalium obtusifolium var. obtusifolium; Gnaphalium obtusifolium Linnaeus var. praecox Fernald
A description of Pseudognaphalium obtusifolium is provided in The Flora of North America.
It is found in medium-sized gaps in a study investigating the interacting effects of overstory removal and ungulate herbivory in a hemlock hardwood forest in Alberta, Michigan.
In the Coastal Plain in Florida and Georgia, P. obtusifolium can be found in mesic hardwoods, turkey oak scrubs, longleaf pine/scrub oak stands, pine flatwoods, bordering cattail marshes, sand ridges, cypress pond margins, annually burned pine savannas, and annually burned mature longleaf pine-wiregrass communities. It can also be found in roadside ditches, and open fields. Soil types include loamy sand, peat soils, sandy loam, and clay soil. Associated species include slash pine, loblolly bay, longleaf pine, wiregrass, Liatris, Panicum, Leptoloma cognata, Polygonella, and Amphicarpum. It has been observed that five to eight years after thinning a longleaf pine stand there was an increase in the frequency of P. obtusifolium.
This species is thought to be dispersed by wind.
Populations of Pseudognaphalium obtusifolium have been known to persist through repeated annual burning.
Herbivory and toxicology
Pseudognaphalium obtusifolium has been observed at the Archbold Biological Station to host wasps such as Cerceris blakei (family Sphecidae).
