Non-native, invasive plants are sometimes the exotic ornamental plants that homeowners and landscapers put in flower beds, yards, and along roadsides. While others are referred to as noxious weeds. Though exotics sometimes look pretty, if they are invasive when they escape into the wild, they can pose serious environmental threats.
