Pseudognaphalium obtusifolium

Pseudognaphalium obtusifolium, synonyms including Gnaphalium obtusifolium and Pseudognaphalium saxicola, is a member of the family Asteraceae. It is found on open dry sandy habitat throughout eastern North America. Common names include old field balsam, rabbit tobacco and sweet everlasting. When crushed, the plant exudes a characteristic maple-syrup scent.

Description
It is a biennial herb which grows up to one meter tall. In its first year, the plant produces tightly packed rosettes covered in wooly hair. In the second year, the plant produces a tall stem with alternate leaves and yellow peg-shaped flowerheads. These are borne in clusters. The seeds are dispersed by the wind. Its native habitats include dry clearings, fields, and edges of woods.

Taxonomy
Pseudognaphalium obtusifolium was first described by Carl Linnaeus in 1753 as Gnaphalium obtusifolium. It was transferred to Pseudognaphalium in 1981.

Populations found in the state of Wisconsin growing on ledges and in cracks in shaded limestone cliff-faces, usually those facing south or east, have been described as Pseudognaphalium saxicola, common name cliff cudweed or rabbit-tobacco. Pseudognaphalium saxicola is listed as Threatened in Wisconsin and is assessed as T2 (Imperiled) by NatureServe, but is regarded by other sources as a synonym of Pseudognaphalium obtusifolium.
