Which plants are poisonous to pets and domestic animals?

I'd particularly like to know which plants should be avoided if you have horses, as well as other household pets such as cats and dogs.


The list of poisonous plants is too long for a short discussion. However, the North Carolina State University has a comprehensive list, with photos:

I would also add that, surprisingly, there are some highly toxic, even fatal plants that have beautiful blossoms and heavenly fragrance, so if you have small children or animals in the house and yard, do a little research before you pick your plants.

A few of these highly toxic bloomers include :

Brugmansia (Trumpet Flower or Angel's Trumpet)
Gelsemium sempervirens (Carolina Jessamine)
Digitalis (Foxgloves)
Laburnum anagyroides (Golden Chain Tree)
Nerium oleander (Oleander)
