Natural range of Pseudognaphalium obtusifolium from USDA NRCS Plants Database.

Description

The common name is Rabbit Tobacco or Sweet Everlasting (Nelson 2005).

Distribution

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 (Holmes and Webster 2011).

Ecology

Habitat

Found on roadsides and disturbed sites, sandhills, and cypress pond margins (Nelson 2005).

An increase in the frequency of P. obtusifolium was observed five to eight years after thinning of a longleaf pine stand (Harrington et al 2011).

Pollination

Mark Deyrup at Archbold Biological Station observed these Hymenoptera species on Pseudognaphalium obtusifolium

Sphecidae: Cerceris blakei
