Atropa Belladonna, a great plant, it's in the same family as the tomato (Solanaceae) which also has poisonous leaves and stems.

I have a couple of yucca plants in my yard with extremely sharp points on their leaves. The leaves contain an irritant that causes a lasting burning sensation. Getting stabbed by one of these guys is a problem.

Lily of the valley is extremely deadly.

The stupid mesquite trees scattered everywhere in my neighborhood, their thorns are way too long for their own good and get stuck deep into your foot because a twig happened to break off into your yard... And then they break off inside your foot and cause infection.

Not to mention the sap that gets into everything and we still can't remove from the car windshield... I hate those things.

Also, mangoes can cause the same rash as poison ivy if you damage anything that isn't the ripe fruit. Found that out the hard way trying to grow one from seed.

Sandbox trees with the exploding tree fruits. Added to do not ever plant list.

Well there’s oleander, digitalis (foxglove), and Manihot esculenta (aka cassava from which we get tapioca).

I'm allergic to life and deathly allergic to majority of outdoor plants does that count as murderous plants? Haha.
