What Is An Invasive Plant?
An 'invasive' plant is a non-native plant that infests natural areas and causes environmental or economic damage, or harms human health. Non-native refers to a plant that does not grow here naturally, but has been introduced from another country or area. Not ALL non-native plants are invasive!
Many invasive plants were initially introduced - with good intentions - for use in landscaping. These plants became invasive when they escaped cultivation and spread rapidly, degrading and destroying thousands of acres of our natural plant communities here in Indiana. Some of these plants are still available commercially!
Below are a few invasive species commonly found in Indiana:
Multiflora Rose (Rosa multiflora) Asian Bush Honeysuckle (Lonicera maacki)
Callery Pear (Pyrus calleryana) Garlic Mustard (Alliaria petiolata)
Autumn Olive (Elaeagnus umbellata) Wintercreeper (Euonymus fortunei)
