The outdoors is full of beautiful plants that can cause serious harm if touched or ingested. This guide covers the most commonly encountered toxic plants in North America.
Poison Ivy (Toxicodendron radicans)
"Leaves of three, let it be." Compound leaves with three pointed leaflets, the middle leaflet on a slightly longer stalk. All parts contain urushiol oil. Use our Plant Identifier to confirm before touching any three-leaved plant.
Deadly Nightshade (Atropa belladonna)
Bell-shaped purple flowers, shiny black berries that look deceptively appealing. Highly toxic — even a few berries can be fatal.
