Maybe you can you this exhaustive list
from the research at Rutgers to plan a deer resistant area...
good luck!

Here is a link that might be useful: Rutgers Deer Resistance

I garden alongside a big herd of deer. I have a water feature -- waterfall and manmade stream. I have a small fenced flower garden and I have lots of flower/shrub gardens outside my fence.

After seeing all the hypericum (St. John's Wort) planted around the Inn at Biltmore, I planted lots of hypericum x hidcote shrubs -- 3x3, mounded, semi-evergreen, yellow blooms all summer. I planted the groundcover (which can be invasive, so I put it in a controlled space) Hypericum calycinum. It's 1x2 and flowers. I've had Hypericum albans purple for awhile and it's nice with the burgundy foliage.

Deer won't eat ferns and those are great around a waterfall in the shade. Astilbe are fine. Farfugium japonicum works. I have cryptomeria and they leave those alone. They haven't bothered my gardenias or heuchera, but they may if hungry enough. Since you're feeding your deer, that may not be a problem.

So far, they've left my Deutzia alone. No problem with crepe myrtles, there are many sizes available. Don't know if you can grow those in the mountains?

There are many ornamental grasses that deer don't like.

They don't eat monarda (bee balm), rosemary, thyme, lavender. They don't eat nepeta, dianthus Bath's Pink, stachys (lamb's ear) or delosperma (ice plant).

They don't eat coreopsis, scabiosa, indigo, salvia.

They don't bother these trees/shrubs: deodar cedar, sweet bay magnolia (though they like to rub on it), southern magnolia (rubbing), osmanthus fragrans, cotinus (smoke tree), butterfly bush.

Best of luck!
