2nd Annual Virginia Retail Garden Center Invasive Plant Survey
From April 1, 2026 - September 30, 2026 the Virginia Invasive Plant Coalition conducted the second annual statewide survey of invasive plants* for sale at retail garden centers. Volunteers submitted observations of invasive plant species found during their visits to garden centers across the state.
Below are the results. Thank you to all the volunteers who made this happen!
