Gaillardia, commonly known as Blanket Flower, is a popular, sun-loving perennial prized for its bright, daisy-like blooms that last throughout the summer. These hardy, drought-tolerant plants are native to North and South America and are a fixture in many low-maintenance gardens. For gardeners in areas with significant wildlife presence, the primary concern is often whether this vibrant flower is susceptible to grazing animals. Blanket Flower is reliably resistant to deer browsing.
Gaillardia’s Natural Resistance to Deer
Blanket Flower is considered highly deer-resistant because of certain defensive characteristics it has naturally developed. Deer are selective foragers, avoiding plants that possess strong odors, bitter tastes, or rough textures. The foliage and stems of Gaillardia species are typically covered in fine, coarse hairs, giving the plant a fuzzy texture that is physically unappealing to a deer’s palate.
This unpleasant texture, known as being “pubescent,” causes a scratchy sensation that deer instinctively dislike. Furthermore, the plant’s leaves and stems contain chemical compounds that give off a strong, bitter flavor and scent when chewed or crushed. These sensory deterrents persuade deer to bypass the plant in favor of smoother-leaved vegetation like hostas or daylilies.
When Deer Might Still Browse Gaillardia
Despite its repellent characteristics, no plant is completely “deer-proof,” and Gaillardia is no exception. A plant’s resistance rating is based on preference, not absolute avoidance. In periods of extreme environmental stress, such as severe drought or heavy snow cover, the deer’s natural foraging hierarchy can shift dramatically.
When a deer’s preferred food sources are scarce, they will resort to eating less desirable plants. Young Gaillardia plants and new shoots are particularly vulnerable, as their foliage has not yet fully developed the coarse, bitter characteristics of a mature plant. These tender, newly established plants can be browsed before they build up their natural defenses, especially by young, inexperienced deer.
Practical Strategies for Deterring Deer
Gardeners can take proactive steps to minimize the risk of deer browsing on Blanket Flower and other landscape plants. One effective strategy is site selection, planting Gaillardia near high-traffic areas or close to the house, as deer are less likely to forage where human activity is frequent. Creating a mixed planting that includes highly aromatic herbs can provide an additional layer of protection.
Plants like lavender, salvia, and rosemary possess scents that deer find offensive. Planting them alongside Gaillardia creates a sensory barrier that discourages entry into the garden bed. For new transplants or in areas with high deer pressure, a temporary physical barrier, such as netting or a small wire cage, can protect the plant until it is fully established. Commercial or homemade deer repellents that use scent or taste deterrents can be applied directly to the foliage, though these require frequent reapplication after rain.
