There are serious problems with aggressive exotic plants which can crowd out more beneficial native species. State laws are in place which prevent the sale of the worst of these species. Nevertheless, they are out in the environment and may threaten existing natural areas and natural landscaping projects. The plant in the photograph is purple loosestrife which, while very attractive, is extremely prolific and can become the dominant plant in wetlands. Purple loosestrife should be removed by hand or with careful, selective, professional application of pesticides that are approved for use near water. European buckthorn and garlic mustard are other species that are causing major problems in the region.
