ARLINGTON COUNTY NATIVE PLANT LIST (Version 9-1-20) The following list of vascular plants are considered native to Arlington County as initially determined through extensive flora inventories conducted from 2005-2009. This document can be considered to be accurate, but not complete. This listing will be updated periodically, identified by (Version Date), as additional species are identified. As work progresses on producing a definitive native flora list, a secondary source for checking the nativity status of a questioned species is the Digital Flora Atlas of Virginia – found at http://vaplantatlas.org/ . It is important to note that some species are periodically reclassified by the scientific community and may experience a change in genus name or family classification. Responsibility for updates and list maintenance resides with the Natural Resource Manager within the Department of Parks, Recreation and Cultural Resources (PRCR).
