Not in Flora of Virginia
A common midwestern dogwood, Swida drummondii is reported as naturalized in northern Virginia by Simmons et al. in Castanea 85: 277-284 (2020).

Flora of the Southeastern U.S. (Weakley et al. 2023) splits traditional Cornus into several genera (Chamaepericlymenum, Benthamidia, and Swida in our area) representing major clades in phylogenetic analysis. Even though Cornus treated broadly is monophyletic, the clades are also monophyletic and diverged millions of years ago, accorrding to Yu et al. (2017, PLOS One DOI:10.1371/journal.pone.0171361) and Fu et al. (2019, Molec. Phylogen. & Evol. 140: 106601). As evolutionary lineages, these clades are far older than many groups treated by taxonomists as genera and clearly merit generic status.
Currently known only from the City of Alexandria and Arlington County. In dry, gravelly soil along old railroad tracks, in wet ditches, and along edges of alluvial swamps, often forming extensive thickets. Believed to have been introduced long ago via the historical rail corridor.
