It's important to acknowledge that deer, like all animals, will eat anything if they're hungry enough. Deer resistant plants are not a normal part of their diet, but under drought and low vegetation conditions deer will devour plants they have ignored for years. A doe with a new fawn won't venture far from it, so she will feed on less-than-desired plants nearby. Also, there are plants that hungry deer will only eat in winter and leave alone the rest of the year.
A deer resistant garden can be abundant and beautiful, but it requires careful plant selection. As I begin planning the landscape for my new house my focus is on gardens that will give me everything I want while denying the numerous deer a tasty lunch.
Generally, deer don't like plants with a strong aroma or with thorns or spines. They tend to stay away from decorative grasses. Many native plants are resistant to deer in areas where deer are native.
Let's begin with deer resistant plants for full sun locations. Lucky for me, many of the plants I like to grow are naturally deer resistant; I have a minor deer problem at my current house and have never had a problem with these plants:
Hens and Chicks
Spirea 'Magic Carpet'
There is no lack of color, texture, and variety in this list. All of them are very resistant to deer in most landscapes. Many of them require little irrigation, which is a plus in my arid region.
Here are some plants for shade or partial shade areas.
I don't currently grow these plants but will in my new landscape. I also plan to add:
The key to identifying deer resistant plants for your landscape is to conduct a little research. Many county Extension offices have fact sheets for local deer resistant plants. The internet allows cross referencing this government information. I easily found that New Jersey, Minnesota, and Colorado Extension information matches my own experience with the plants listed above.
I have a gardening friend who likes to grow Arborvitae and has to fence in each plant to prevent damage; Arborvitae is on the list of plants deer like to munch. I've tried to grow cherry, apple and plum trees in my current landscape and the deer have devastated them; they'll even push through the protective netting to nibble the buds. Those of us who have built structures to try and keep deer out will gladly share our experience.
Asking for advice can save valuable time, energy, and money. Geraniums cover the gamut of deer preference. Some varieties of geranium are like candy to deer while others are like vinegar. Find out what your friends are growing and copy their successes. I haven't seen Asian Lilies on any deer resistant plant list, but in my neighborhood they leave all of mine alone.
I also believe in creative sacrifice. If you want to grow plants that deer may like to eat, also grow plants that they definitely like to eat. Grow plants like wild strawberries, raspberries, Virginia creeper, and sunflowers as a friendly offering. When they venture into your yard they'll gravitate toward those tasty morsels and are more likely to leave your treasured plants alone.
