deer-resistant plants: resource lists for gardeners

White-tailed_deer_(Odocoileus_virginianus)_grazing_-_20050809 (1)WE ALL WANT the cheatsheet—the list that simply, clearly spells out the plants we can feel confident planting, even if deer may visit the garden, even if we have no fence. And the list of deer-resistant or deer-proof plants must be location-specific, for “our” deer, of course.

Matters of regionality, seasonality and even aberrant weather patterns can change what deer eat, so no two regions or even areas within a region have the same list of “safe” plants, nor is the “safe” list even safe perennially in the same spot. Under duress, in shifting circumstances—from drought, snowload, you name it—deer will at least try eating anything, it seems.

Generally speaking, you’re safest with plants that are aromatic (think mint, or Artemisia); plants that have latex sap; or are even rated as “poisonous” (Narcissus is a commonly cited example). But biologists have demonstrated that deer do, in fact, eat some toxic plants with no ill effect, especially in spring, probably owing to various factors including the animals’ gut chemistry, stomach structure and even how they practice “cautious sampling” (rather than gorging on too much of something all at once). Fascinating—though not very helpful to us as gardeners wishing to protect the bed or border.

Many native plants seem to resist wildlife pressure compared to garden ornamentals of an introduced nature—but then deer in Alaska, for instance, eat skunk cabbage (despite the toxins/oxalic acid it contains). There are many such examples, and actually concerns, that increased deer browse by larger populations is negatively affecting native forest vegetation, especially in the East. Penn State, the Harvard Forest and others are conducting longterm studies.

But back to the smaller matter of the garden: Fuzzy leaves or spiny parts may help discourage browsing, too (but I know: they ate your roses, so who am I kidding?). Again, all the suggested guidelines are just that: suggestions, not ironclad solutions.

woven-wire-fenceHaving been gnawed into submission many years ago, I’m a fencer—not a swordsman, but someone who lives behind an 8-foot fence (here’s my page about fences, the ultimate deer protection). My friend Adam Wheeler of Broken Arrow in Connecticut is a nurseryman whose job is to search for cool new plants for customers. Many of those people shop for deer-resistance specifically, and garden unfenced as Adam does–offering these insights about what works (including all the plants below, and many more).

I’VE GATHERED references below, and though I’ve mostly grouped them by region, I suggest browsing outside your zone because you’ll start to notice commonalities–plants that seem to work everywhere, which makes them a really good bet.
