Deer-Resistant Plants

Posted 2/9/2016

Carol asked me recently "Are there any flowers that deer won’t eat?" This is a question I am asked repeatedly. Are there any deer resistant plants? Well, it depends. A sufficiently hungry deer will find almost any plant palatable. The Sunset Western Garden Book states "deer in different areas may have different tastes." They report that deer seem to shun the following perennial plants: aster, big sagebrush, beebalm, black-eyed Susan, boxwood, broom, buckwheat (Eriogonum sps.), butterfly bush, coreopsis, crocus, currant, daffodil, daylily, foxglove, heavenly bamboo, iris, juniper, Jupiter’s beard, lavender, lilac, lupine, Oregon grape, penstemon, phlox, poppy, potentilla, pyracantha, quince, red-hot poker, Serbian bellflower, smokebush, snow-in-summer, spiraea, St. John’s wort, sweet woodruff, sumac, tulips, viburnum, vinca and yarrow. Sunset also lists ash, cedar, cypress, fir, hackberry, hawthorn, oak, pine, spruce and western redbud as deer-resistant trees. Other references list a few additional plants.

However, if you have deer in your area and any of the above listed plants, I’m sure you have seen deer eat even supposedly deer resistant plants.

While planting a landscape with plants less appetizing to deer is a great beginning to deer proofing your yard, fencing and exclusionary tactics are the best ways to ensure that deer stay away from plants. Not just any fence will do. An 8-foot fence, a double offset fence, slanted seven-wire fence or electric fence are recommended. Fencing has to be properly constructed. Or, individual plants can be protected with woven wire cages. Scare tactics, such as dogs, only provide temporary relief. As soon as the dog is gone, the deer return.

A wide variety of repellants is available. Some repel by smell, others by taste. Some are applied directly to plants, while others are applied over an area. Area repellants are usually less effective than contact ones. Dormant application is sometimes recommended. Since regular applications are required, costs can be high and effectiveness is variable. Rainfall can reduce the benefits of a repellant. Repellants reduce damage, but rarely eliminate it. If a deer is hungry, bad taste or strong odor won’t keep it away from your plants.
