Invasive Shrubs edit
This article deals only with invasive shrubs in the Midwestern United States. For invasive shrubs in other areas, do a Wikipedia search for the specific plant species.
An invasive plant is defined by the Invasive plants of Wisconsin as simply a plant out of place.
Invasive shrubs can be either nonnative or native. Nonnative shrubs are often of most concern because they tend to take over and dominate an area. However, some native shrubs are also undesirable or potentially undesirable and can be considered invasive.
