Sorry, none of these are good answers. I want to know plants that are not eaten by any herbivores. Hemidy? That’s not even a plant, is it? Sorry belladonna doesn't work as an answer - herbivores are more resistant than carnivores, indicating that this plant can if fact be eaten. Same with poison ivy - to a minor extent, the foliage, branches, and fruit are eaten by the Black Bear, Cottontail Rabbit, and White-Tailed Deer. These animals appear to be immune to the irritating properties of the chemical agent, urushiol, in the foliage. Poinsettas aren’t poisonous at all, according to a research study conducted at Ohio State University, which conclusively proved that all parts of the plant are non-toxic.

Plants survive by adapting to the environment. If the local fauna is eating the plant, the plant will develop a toxicity to ward off such animals form dining on the plant or the plant will reproduce in such numbers that a bite here and there doesn't matter.
The trick comes in when the animal develops a bond with a particular plant and adapts to the toxicity and uses this plant toxin to form its own shield against its predators--such as Monarch Butterflies and Milk weed or Gulf fliterary butterflies and the corky stemed passion flower.
