Virginia Bluebells (Mertensia virginica) are a cherished sign of spring, emerging as vibrant, bell-shaped flowers in shades of blue, pink, and lavender. These native wildflowers bloom briefly, typically from March to May, before their foliage recedes by early summer. Gardeners often seek to include these ephemeral beauties in their landscapes, leading to a common question about their susceptibility to deer browsing.
Virginia Bluebells and Deer Resistance
Virginia Bluebells are generally considered resistant to deer browsing. This resistance is often attributed to the presence of certain compounds, such as alkaloids, which can make the plants unpalatable or even mildly toxic to deer if consumed in significant quantities. Consequently, Virginia Bluebells are rarely a primary food source for deer, making them a favored choice for many gardeners in areas with deer activity. While deer may avoid them, Virginia Bluebells are also known to be resistant to rabbits.
Factors Influencing Deer Browsing
Despite their general resistance, deer browsing on Virginia Bluebells can occasionally occur under specific environmental conditions. When preferred food sources are scarce, such as during harsh winters, prolonged droughts, or in areas experiencing overpopulation, deer may resort to eating plants they would typically avoid.
Newly established or very young Virginia Bluebell plants can be more vulnerable to browsing. Their tender new growth might be more appealing to deer than the mature foliage. High deer population densities in an area can also increase browsing pressure on all plant types, including those typically considered deer-resistant.
Protecting Your Virginia Bluebells
For gardeners concerned about potential deer browsing, several proactive measures can help safeguard Virginia Bluebells. Temporary physical barriers, such as netting or fencing, can be effective, especially for new plantings or in areas with high deer traffic. A fence at least 7 to 8 feet tall is recommended to deter deer from jumping over. For individual plants or smaller beds, a more localized cage or netting can provide adequate protection.
Applying deer repellents is also a viable strategy. These products work by emitting foul odors or creating an unpleasant taste, discouraging deer from consuming the plants. Regular reapplication is necessary, particularly after rain or new plant growth, to maintain effectiveness. Alternating between different types of repellents can prevent deer from becoming accustomed to a single deterrent. Planting Virginia Bluebells alongside other highly deer-resistant species with strong fragrances or unpalatable textures can create a less appealing environment for deer.
