Here are some plants that deer, hares, rabbits, and other mammals are known to dislike eating. These species often have bitter tastes, tough or fuzzy textures, strong aromas, or naturally occurring compounds that make them less appetizing—or even mildly toxic—to browsing animals.
The list is not set in stone, however. Mammals can have very different tastes depending on the region, and in some areas, they may learn to eat plants they typically avoid elsewhere. Also, when food is scarce—especially at the end of a harsh winter or in areas where mammal populations are unusually high—even these “resistant” plants may get nibbled.
Still, if the bulk of your gardening is done with the following plants, you’ll greatly reduce the risk of mammal damage. For even better protection, especially with young or newly planted specimens, physical barriers such as fencing or netting may be helpful until plants are well established.
