Fountain grass (Pennisetum alopecuroides) is a favored ornamental grass, admired for its graceful, arching foliage and distinctive, bottlebrush-like plumes. A common concern for those cultivating this attractive plant, especially in areas frequented by wildlife, is whether deer will browse it. This article aims to address that query and provide practical insights for protecting your fountain grass.
Is Fountain Grass Deer Resistant
Fountain grass is generally considered deer resistant. Deer typically avoid this ornamental grass due to its unpalatable characteristics. Its coarse texture and fibrous blades are not appealing to deer, and some varieties have a bitter taste.
While fountain grass is broadly resistant, no plant is entirely deer-proof. Deer can be persistent, especially when preferred food sources are scarce, leading them to sample plants they would normally ignore.
Factors Influencing Deer Browsing
While fountain grass deters deer, certain environmental conditions can influence browsing behavior. Food scarcity is a primary factor; during periods of drought, harsh winters, or high deer populations, usual food sources may become limited. Under such pressure, deer may eat plants they would typically avoid, including fountain grass, to meet nutritional needs.
Plant maturity also plays a role. Young, tender fountain grass plants might be more susceptible to browsing than established, mature specimens with tougher foliage. Some fountain grass varieties could be more palatable to deer due to subtle differences in their chemical composition or texture. If deer are extremely hungry, they may consume almost any available vegetation to survive.
Protecting Your Fountain Grass from Deer
To minimize deer damage to fountain grass, several proactive measures can be implemented. Physical barriers, such as fencing, offer reliable protection. A fence should be at least 8 feet tall to deter deer, as adult deer can jump considerable heights.
Deer repellents provide another layer of defense and come in various forms. Scent-based repellents use odors unappealing to deer, like garlic or rotten eggs. Taste-based repellents make plants bitter or unpleasant upon consumption. These repellents require regular reapplication, especially after rain, to maintain effectiveness.
Strategic planting can also help. Incorporating aromatic or unpalatable plants, such as rosemary, lavender, or marigolds, near fountain grass creates a sensory barrier. Planting fountain grass in locations with regular human activity or less accessible garden areas can naturally reduce its appeal to deer.
Alternative Deer-Resistant Grasses
For gardeners seeking other deer-resistant ornamental grasses, several alternatives to fountain grass are available. Maiden grass (Miscanthus sinensis) is recognized for its tough, fibrous leaves and low palatability to deer. Switchgrass (Panicum virgatum) offers strong resistance due to its coarse texture and tall, dense growth habit.
Little bluestem (Schizachyrium scoparium) is a native option known for being deer and rabbit resistant, thriving even in challenging conditions. Blue oat grass (Helictotrichon sempervirens) provides attractive blue-green foliage and is avoided by deer, making it suitable for bordering gardens. These grasses offer diverse textures and forms.
