This title is somewhat misleading. Deer will eat or sample (nibble) on any landscape plant, particularly if they are hungry enough. Deer also do not read lists of plants they’re suppose to leave alone.
The following list of deer resistant plants is a sampling from reports across the U.S. It does not include every tree reported. Deer species and numbers vary across this big country. A deer’s food palate may also differ from one region to another. It also depends on how hungry the numbers of deer in an area may be.
Some native trees such as American beech, buckeyes, green ash, persimmon, hophornbeam, and flowering dogwood are important food resources for deer and other wildlife. But, they do little significant damage to their host tree(s). If you are trying to introduce young host trees into a landscape, you should fence them off for 3-5 years until they become larger and better established. Finally, prune up low branches out of reach of deer feeding.
Abnormally high deer populations starved for a lack of their favorite foods (mast) will eat or browse on almost any plant. This is a survival reaction. To truly protect plants from deer when deer numbers are unusually high, a tall fence or reinforced netting may be your best options.
