Deer resistance in plants is not an absolute guarantee but rather a spectrum of tolerance. It refers to a plant's possession of certain characteristics that make it unpalatable or undesirable to deer. These traits are the plant's natural defense mechanisms, evolved to deter herbivores. Deer are opportunistic browsers and will sample almost any plant, especially in times of extreme hunger or when their natural food sources are scarce. Therefore, a plant labeled "deer resistant" is one that deer typically avoid, making it a lower-risk choice for landscapes in areas with high deer pressure.
African Daisies (Osteospermum spp.) are generally considered to be deer resistant. This classification stems from the physical and aromatic properties of the plant. The foliage of many Osteospermum varieties is slightly fuzzy or hairy, a texture that deer find unpleasant to eat. More significantly, the plant emits a distinct, pungent aroma when its leaves are brushed or crushed. This scent, while often pleasant or neutral to humans, is a strong deterrent to deer whose sensitive sense of smell identifies it as unpalatable. Consequently, deer will typically bypass African Daisies in favor of more tender, sweet-smelling plants in your garden.
African Daisies are herbaceous perennials, often grown as annuals in colder climates across the US. They are prized in landscaping for their vibrant, daisy-like flowers that come in a stunning array of colors, including purple, pink, yellow, and white, often with contrasting centers. They thrive in full sun and well-draining soil, making them excellent choices for sunny borders, rock gardens, and containers. Their growth habit is typically mounding, and they provide a long season of prolific blooms from spring until the first frost, especially with deadheading.
When incorporating African Daisies into a landscape where deer are prevalent, strategic placement is key. For the greatest effect, use them as part of a layered defense. Plant them alongside other well-known deer-resistant plants such as lavender, salvia, Russian sage, and ornamental grasses. This creates a garden-wide aroma and texture profile that is broadly unappealing to deer. Furthermore, consider positioning African Daisies closer to the home, in raised beds, or near patios and walkways where human activity is frequent, as deer are naturally wary of these areas. While no plant is entirely deer-proof, using African Daisies as a frontline plant can help protect more susceptible species planted behind them.
To build a truly resilient landscape, pair African Daisies with other plants that share similar growing conditions and deer-deterring qualities. Excellent sun-loving companions include Coreopsis (Tickseed), which has a similar flower form but fine, feathery foliage; Echinacea (Coneflower), with its coarse texture and spiky center cone; and Nepeta (Catmint), which releases a strong minty scent. For added foliage texture and scent, interplant with Perovskia (Russian Sage) and Santolina. This approach not only creates a visually dynamic and colorful garden but also establishes a powerful aromatic barrier that is more effective than relying on a single plant species.
