This type of phlox is known as "creeping phlox" or "ground phlox," to distinguish it from the much taller perennial known as "garden phlox." Many ground covers boast, first and foremost, a usefulness in suppressing weeds or controlling soil erosion, including evergreen shrubs such as Blue Rug juniper and Blue Star juniper. But ground phlox plants are not only useful, they're also very colorful (in spring, at least). There are a number of colors from which to select when buying ground phlox. Many people plant ground phlox in color combinations. I especially like the pink and white combination, which reminds me of Good & Plenty candy! But the color combination shown in the photo above is no slouch, either!
