Plants to Watch

This list includes species that exhibit those traits shared by a number of invasive species. While they may not be invasive in all regions of the country, they bear careful observation and reporting. For information on evaluating the invasive potential of ornamental plants, Sarah Reichard, University of Washington, has developed guidelines. For a copy of the guidelines, see Reichard, S. 1999. A Method for Evaluating Plant Invasiveness. The Public Garden 14(2):19-21.
