Creeping phlox is a popular groundcover, celebrated for its vibrant spring blooms. Many gardeners wonder about its susceptibility to deer browsing. Understanding how deer interact with this plant helps maintain its beauty in the landscape.
Understanding Creeping Phlox and Deer
Creeping phlox (Phlox subulata) is generally deer-resistant, meaning it’s not a preferred food source. This resistance stems from characteristics deer find unappealing. The foliage has a distinct pungent aroma, acting as a natural deterrent. Its leaves also have a fuzzy or coarse texture, and some varieties may contain sticky sap or small needle-like hairs, contributing to an unpleasant mouthfeel.
Despite these qualities, “deer-resistant” does not mean “deer-proof.” While deer usually avoid creeping phlox, they may occasionally sample it. Most gardeners observe that deer leave their creeping phlox untouched, confirming its unappealing nature.
Factors Influencing Deer Foraging
While creeping phlox typically deters deer, certain environmental conditions can compel them to browse on plants they would otherwise ignore. Extreme hunger, often occurring during harsh winters or prolonged droughts, can lead deer to consume almost any available vegetation. In such circumstances, even creeping phlox’s unpalatable characteristics may not prevent some nibbling.
Young, tender plants might be more vulnerable than mature ones, as their developing foliage may lack full deterrent qualities. Regional variations in deer populations and their dietary habits also play a role. A local deer population accustomed to limited food sources might be less discerning, occasionally resorting to plants usually left alone.
Strategies to Deter Deer
If deer browse on creeping phlox, gardeners can employ various strategies. Deer repellents are common, with options including scent-based formulas with strong odors like garlic, rotten eggs, or mint. Taste-based repellents, containing bitter or spicy substances like capsaicin, make the plant unpalatable upon contact. These repellents typically require reapplication, especially after rain or new plant growth.
Physical barriers offer a reliable solution, especially for new plantings. Netting or individual plant cages can shield vulnerable plants, while a sturdy, eight-foot fence protects larger areas. Some gardeners also use “psychological” fences, employing thin wires or fishing lines at various heights to deter deer without a solid structure.
Companion planting involves interspersing creeping phlox with other unpalatable plants. Aromatic herbs like lavender, catmint, garlic, chives, mint, rosemary, or marigolds can be planted nearby. The strong scents can mask the presence of creeping phlox, creating a less appealing environment for deer.
Deer-Resistant Alternatives to Creeping Phlox
For additional deer-resistant groundcover options, several alternatives offer similar aesthetic appeal. Sedum (stonecrop) is a popular choice, known for its thick, fleshy leaves and often bitter taste. Varieties like ‘Autumn Joy’ are noted for their deer resistance and drought tolerance.
Barrenwort (Epimedium) is another excellent deer-resistant perennial, rarely bothered by browsing. This tough woodland groundcover features attractive foliage and delicate flowers, thriving in shaded conditions where other plants might struggle. Barrenwort is consistently rated as one of the most deer-resistant plants available.
Lamium (spotted deadnettle) provides a versatile, shade-tolerant, deer-resistant groundcover. It forms spreading patches of distinctive leaves, often with silver variegation, and produces charming hooded flowers. Lamium is vigorous yet generally not invasive, making it suitable for creating a tapestry effect beneath trees or along garden edges.
