The Massachusetts Invasive Plant Advisory Group is out with an updated list of invasive plant species. The original list had 38 species - the updated version has 66, and now lists such perennial favorites (hee hee :-)) as kudzu (Pueraria montana), burning bush (Euonymus alatus) and giant hogweed (Heracleum mantegazzianum). An interesting and informative addendum to the list is a list of species that were evaluated but not determined to be invasive. It's good (but rare) to see that kind of data included in a large-scale invasives risk assessment. For those of you that recognize many of your own "perennial favorites," the New England Wildflower Society offers a document called "Alternatives to Invasive Species."
