Flora Project Logo 

The Department of Recreation, Parks and Cultural Activities' Horticulture and Natural Resources Section surveyed the vascular flora of Alexandria from 2002 - 2009.  In addition, the team searched herbaria for historical collections that reflected taxa native to the City.  These surveys and collections yielded more than 800 native vascular plants representing 366 genera and 128 families.  Currently available is the Flora Project in pdf form, a graphic presentation called "Vanishing Flora of Washington and Vicinity" which introduces the Flora Project, and a map of Alexandria's surficial geology.  Check back for an upcoming searchable database of flora found in Alexandria.
