Deer resistant plants and trees.
If you need to plant trees and shrubs that can resist deer, here is a list of garden / landscape plants that increase the deer resistance in your yard.
No garden is 100% deer resistant because different deer have different preferences. The idea of "deer proof" is more of a figure of speech than reality. Sometimes a plant or tree will be unpalatable when it's older, but may be palatable to deer when that plant is young.
Deer eat foliage as well as berries or fruit. One year, I performed 2 days of pruning around a home in Central Point, Oregon, on a 2 acre property. The branches were brought downhill through a gate, to burn piles on the lower half of the property, outside the fence. Less than 15 minutes after the branch piles began to grow, a "pack" of about 12 deer converged on the piles and fed on the foliage of landscape tree and shrub foliage on the cut limbs. The deer fed from the piles for days.
If you want a small garden of susceptible plants in a deer-rich environment, consider using a hedge or fence to enclose a landscape area - maybe a 5' high barrier that can't be seen through. Apparently, deer don't like to jump over a barrier that prevents them from seeing the other side. An enclosed landscape area like this could have virtually any kind of landscape design.
This will give you a head start. Feel free to look-up these plants in a gardening book or plant encyclopedia to see what zones they grow in, as well as water and shade requirements. For a few, I included common names. In a garden book, when you look for care and climate needs, you will find common names.
The plants listed below are considered a good choice for "deer country". The genus or species names are listed first; the common name second.
A partial or severe shortage of forage food can cause deer to devour almost any plants including the ones generally known to be deer resistant.
