THE NATURAL LANDSCAPING ALTERNATIVE:
An Annotated Slide Collection - Slide 34
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. |
