There are several species of poisonous plants that may be found growing along our highways. While most of these can produce pain and itching that will last a few hours to a few days, some, such as the Giant Hogweed at right, cause blisters, burning and scarring that may last for several years. These pages are intended to help travelers and workers recognize which plants should be avoided.
BE SAFE!
Protect yourself and your children from these dangerous plants.
NOTE: The arm extending from the grinning worker in the rear is well beyond the poisonous leaf.
