State Arboretum of Virginia at Blandy Experimental Farm Landscape Plants that are Alien Invasive Species in Virginia

The following list contains alien invasive plants that are grown and/or used in the Horticulture/Nursery industry. Plants that are not grown and distributed through the industry (such as Alliaria petiolata, Garlic Mustard) do not appear on this list. This list was composed from the Mid-Atlantic Exotic Pest Plant Council list of alien invasive plant species. Please see http://www.invasive.org/maweeds.cfm for the complete list. A majority of the following plants are reported as invasive in Virginia. The few that are not reported as so, appear on this list because they are reported as invasive in multiple neighboring states (Maryland, West Virginia, North Carolina, Tennessee, Kentucky and/or Pennsylvania) and have been witnessed by staff as being invasive in Virginia. Please note that cultivars of these plants can also be invasive.
