Etymology
The species name was originally cited by Linnaeus as ''Chionanthus virginica'', treating the genus as feminine; however, under the provisions of the ICBN
The ''International Code of Nomenclature for algae, fungi, and plants'' (ICN) is the set of rules and recommendations dealing with the formal botanical names that are given to plants, fungi and a few other groups of organisms, all those "trad ...
, the genus is correctly treated as masculine, giving the species ending as ''virginicus''.[Germplasm Resources Information Network]

Cultivation and uses
Although native in the southeastern United States, it is hardy in the north and is extensively planted in gardens, where specimens are often grown with multiple trunks. The white flowers are best seen from below. Fall color is a fine, clear yellow, a good contrast with viburnum
''Viburnum'' is a genus of about 150–175 species of flowering plants in the moschatel family Adoxaceae. Its current classification is based on molecular phylogeny. It was previously included in the honeysuckle family Caprifoliaceae.

s in North America. Since then, emerald ash borer has been found in white fringetrees in Illinois, Indiana, Ohio, and Pennsylvania, indicating to researchers that white fringetrees are being utilized by emerald ash borers throughout the range where the species overlap. Symptoms of infestation include crown dieback and epicormic sprouting.[Peterson, Donnie L., and Don Cipollini]
