Plant Profile: Creeping Phlox (Phlox stolonifera)

Phlox_stolonifera_Creeping phlox is an herbaceous perennial native to southeastern US where it grows in the woodlands and moist areas of the Appalachian Mountains. It forms large mats of low growing evergreen foliage that are topped by loose six inch wide clusters of blue, lavender, white or pink flowers in spring. The flowers are fragrant and have rounded unnotched petals around a yellow center. They are about an inch across and are carried on stems six to twelve inches tall. The flowers are an important source of nectar for hummingbirds and swallowtail butterflies. The deep green leaves are ovate to round and differ in size with the ones on the creeping sterile stems measuring 1.2-1.8 inches long and those of the erect flowering stem measuring .72 inches. Creeping phlox is an excellent choice for a woodland garden and can be used as a groundcover. If it likes the site it well readily self-sow.
