Do Deer Eat Coreopsis?

Written by: Gemmali Dizor

As a gardener, it’s essential to understand the dietary habits of deer to protect your garden from damage. If you’re growing coreopsis, you may be wondering whether deer will eat them. The answer is yes, deer do eat coreopsis. However, some varieties of coreopsis are less palatable to deer than others, so it’s essential to choose the right type of coreopsis to plant in your garden.

The Tastiness of Different Types of Coreopsis

Deer are known for their indiscriminate eating habits, but not all plants are equal in their eyes. Some plants are highly preferred by deer, while others are less appealing. When it comes to coreopsis, the taste can vary depending on the variety.

For example, Coreopsis verticillata, commonly known as threadleaf coreopsis, is a favorite among deer. On the other hand, Coreopsis grandiflora, or large-flowered coreopsis, is less appealing to deer and is often considered deer-resistant.

The Reason Behind Their Preference

Deer have a keen sense of smell and taste, and they use these to identify which plants are palatable and which are not. The chemical composition of different varieties of coreopsis can play a significant role in their preference. For instance, some coreopsis varieties contain compounds that are bitter or unpalatable to deer, making them less likely to be eaten.

Factors That Affect Deer Feeding Habits

While deer have their preferences, there are several factors that can impact their feeding habits. For example, the availability of food can influence deer to eat plants that they might not normally consume. When food sources are scarce, deer will eat nearly anything, including coreopsis.

The population density of deer in a particular area can also impact their feeding habits. When there is a high density of deer in an area, they will be more likely to eat a wider range of plants, including coreopsis.

Protecting Your Coreopsis from Deer

If you want to protect your coreopsis from deer, there are several steps you can take. One option is to plant deer-resistant varieties of coreopsis, such as Coreopsis grandiflora. Another option is to use physical barriers, such as fences or netting, to keep deer away from your garden.

You can also use deer repellents, such as sprays or granules, to discourage deer from eating your plants. Some gardeners find success with natural deer repellents, such as bars of soap or human hair tied to plants, while others prefer commercial products.

The use of motion-activated sprinklers can also be an effective deterrent for deer. These devices will activate when a deer approaches, startling them and causing them to retreat.


In conclusion, deer do eat coreopsis, but some varieties are less palatable to them than others. If you want to protect your coreopsis from deer, consider planting deer-resistant varieties, using physical barriers, or applying deer repellents. By taking these steps, you can enjoy a thriving garden full of beautiful coreopsis without the worry of deer damage.
