This hybrid has nice shiny dark-green leaves and grows 10" to 12" tall in sprawling mounds. Lavender-blue petals surround a contrasting red eye on this late-spring bloomer. Chattahoochee phlox, believed to be a hybrid of downy phlox (Phlox pilosa), provides a lively color contrast as it blooms from late spring into summer. A perennial that provides lavender accents.
