The non-native plants listed below are either well-documented invasives or potentially invasive plants in Michigan. Once introduced, these plants have the potential to aggressively colonize natural areas, decrease biodiversity and compromise the ecological integrity of the intact ecosystems they invade. Invasive plant species have impacts above and beyond just simple competition. Some invasive species alter hydrology, others impact nitrogen balance or fire ecology to name just a few negative impacts on the greater landscape. The potential invasiveness of a particular species depends on many factors including geographic location, soil type, and the relative disturbance of the site.
MNPPA member nurseries are restricted from cultivating these plants and are expected, through active management, to prevent the distribution of plants and seed in the plant material they sell.
