#1. Creeping Phlox Naturally Suppresses Weeds

Who likes dealing with pesky weeds? Not us! Creeping phlox is a fast-spreading and hardy ground cover that has been used by gardeners to naturally suppress weeds in their garden or landscape. The secret is in the soil. It’s a carpet of flowers chokes out weeds by stretching underground through the soil. Once established, ground covers like creeping phlox begin suppressing weeds by giving them no space to grow – essentially crowding them out. 

Try weeding before planting your creeping phlox during the spring or fall – this should help with suppression and keep weeds at bay next bloom.

#2. Winterizing Creeping Phlox Is a Breeze

Not only is winterizing creeping phlox a breeze: it’s practically nonexistent! No special care is needed to protect creeping phlox in the winter. Even when frigid temps and frost hit your plants, roots still remain alive deep within the soil. In fact, snow provides a nice blanket of protection to your creeping phlox throughout the winter months, so don’t bother knocking it off your plants. 

If you wanted to give your creeping phlox some special attention, try pruning your phlox by cutting them back once the flowers have faded. Otherwise, this plant will do just fine throughout the winter if you decide to pay it no mind.

#3. Creeping Phlox Is Pet & Pollinator Friendly

When searching for plants for your garden you may be shocked at the number of plant varieties that are toxic to dogs, cats, and other animals. According to the ASPCA, the systemic effects of toxic plants on animals can cause vomiting and other gastrointestinal issues.

That isn’t the case for creeping phlox. This plant powerhouse is both pet and pollinator friendly, so you can not only ensure your fury friend stays safe, but you can also give yourself a pat on the back for promoting an environment for native wildlife like bees and butterflies. As an added bonus, this non-toxic variety is also deer resistant, meaning they likely won’t bother messing with your plants. Watch out for rabbits though!

#4. There Are Over 60 Species Of Phlox

You may know about the variety of colors of phlox, but did you know about the several different species that permeate these beautiful hues? There are over 60 species of Phlox, including Phlox paniculata (garden phlox), Phlox divaricata (woodland phlox), and Phlox adsurgens (northern phlox). Native to North America and Eastern United States, most varieties of phlox thrive in areas of full-sun and fairly moist soil.

Unlike its family members, creeping phlox (Phlox subulata) grows closer to the ground, reaching about 6 inches in height at a maximum. Plant them alongside tall garden phlox, like ‘Cloudburst’ or Luminary™ ‘Backlight’ which can reach up to 30″ tall at maturity!

#5. Creeping Phlox Is An Excellent Choice For Slopes & Hillsides

Ground covers in general make excellent choices for slopes and hillsides. It can be difficult maintaining gardens alongside sloped landscapes. Still, creeping phlox requires minimal maintenance after planting, meaning you won’t have to climb any steep hills often to keep these plants alive and well. Just opt for a garden hose nozzle for safe watering!  

As an added bonus, creeping phlox and other ground covers are excellent at preventing erosion on slopes and hillsides because their spreading roots hold soil in their place. This can be ideal for environments with heavy rainfall.

#7. Creeping Phlox Is Beautiful Even After Bloom

We can’t get enough of plants with garden appeal year-round, and creeping phlox is no exception. Creeping phlox foliage will develop vibrant green leaves after they are done blooming before going dormant in the winter. In addition, its mossy look (i.e., the name moss phlox) adds an earthy appeal to your garden. This makes phlox a fantastic addition to a cottage landscape by adding an “overgrown look” to rock and retaining walls as it creeps down the sides.

Because of its thick mossy texture, phlox can handle a high volume of foot traffic during after its bloom and before its dormant period.
