Solomon’s Seal, with its graceful arching stems and bell-shaped flowers, is a favored choice for many shade gardens, admired for its elegant form and adaptability. Gardeners often seek out plants that thrive in dappled light, and this perennial fits the description beautifully. A common concern for gardeners, however, is whether deer pose a threat to the plant’s delicate foliage.
Understanding Deer and Solomon’s Seal
Solomon’s Seal (Polygonatum species) is generally considered deer-resistant; deer typically avoid browsing on it. This resistance is attributed to compounds within the plant’s tissues, which impart an unappealing taste or texture. It contains saponins and cardenolides, which, while not highly toxic in small amounts, can cause mild digestive upset or simply taste unpleasant, leading deer to seek more palatable food. Its unpalatability discourages sustained browsing, making it a safe addition to gardens in deer-prone areas.
The plant’s sap and mature leaf texture also contribute to its avoidance by deer. While young, tender shoots might occasionally be nibbled, established plants with firmer leaves are less appealing. This characteristic makes Solomon’s Seal a preferred choice for gardeners minimizing deer damage to their landscape. No plant is entirely deer-proof, but Solomon’s Seal consistently ranks high among those rarely bothered.
Factors Influencing Deer Browsing
While Solomon’s Seal is largely unappealing to deer, environmental conditions can influence browsing behavior. During periods of extreme food scarcity, like harsh winters or prolonged droughts in summer, deer may deviate from typical dietary preferences. When primary food sources become scarce, deer are driven by hunger to consume plants they would normally ignore, including deer-resistant ones.
The age and growth stage of Solomon’s Seal can also play a role in its vulnerability. Young, newly emerged shoots in spring are often more tender and succulent than mature foliage, potentially making them slightly more attractive to desperate deer. In areas with exceptionally high deer populations, competition for food intensifies, leading to increased browsing pressure on a wider variety of plant species, even those typically avoided. Under these specific circumstances, the plant’s usual deterrent qualities may not be sufficient to prevent some damage.
Protecting Solomon’s Seal from Deer
For gardeners experiencing deer browsing on Solomon’s Seal, several practical strategies can help protect the plants. Physical barriers, such as temporary netting or a permanent fence, can effectively exclude deer from vulnerable areas, especially when plants are young or in locations prone to heavy browsing. Even a simple mesh draped over emerging plants in spring can offer significant protection during their most tender stage.
Commercial deer repellents can also deter browsing by altering the plant’s taste or scent. These products often contain ingredients like putrescent egg solids or capsaicin, making the foliage unappetizing or irritating to deer. Regular reapplication, especially after rain or new growth, is necessary for these repellents to maintain their effectiveness. Planting Solomon’s Seal alongside other highly unpalatable plants, such as those with strong aromas or prickly textures, can create a less appealing environment for deer, forming a natural deterrent barrier. Positioning Solomon’s Seal closer to the house or in areas with frequent human activity can also reduce deer visits, as deer generally prefer to forage in quieter, less disturbed locations.
