Article contributed by SLELO partner, Sue Gwise with the Cornell Cooperative Extension of Jefferson County Most of us think of invasive plants as those that invade natural areas.  You may be surprised to know that your landscape may be harboring invasive species that were intentionally planted. Many invasive plants are still sold by nurseries and garden centers.  Some common invasive landscape species are now regulated or prohibited by the Department of Environmental Conservation. Regulated plants can be possessed but not knowingly released into natural areas, while prohibited plants can not be sold, bought or possessed in New York State. View a full list of regulated and prohibited plants in NYS. If you do decide to remove any invasive landscape species, below is a list of native replacements.  If you are starting a new landscape project, do not plant the species listed below. Try to favor native plants as much as possible to take advantage of the following benefits:
  • Native plants support native wildlife. 90% of all songbirds raise their young on caterpillars that feed on native plants.
  • Native plants are lower maintenance as they are adapted to our climate conditions and have fewer diseases and insect issues.
  • A healthy population of native plants can deter invasion from invasives to an area.
