Noxious Weeds

Noxious weeds are plants that are not native to our area. Most have come from Europe or Asia either accidentally or as ornamentals that have escaped. These plants have an advantage because the insects, diseases, and animals that normally controls them are not found here. Because these plants have developed specialized mechanisms to survive, they spread at an alarming rate.
