Phlox paniculata ‘Robert Poore’

5 Photos


Phlox paniculata ‘Robert Poore’ is named after the landscape architect who discovered it at an abandoned homestead in Mississippi decades ago. He shared it with Barbara Boys of Southern Perennials and Herbs who recognized its superior performance and introduced it to the nursery trade. Phlox paniculata ‘Robert Poore’ grows as tall as 5′ and bears large, broadly pointed, magenta colored inflorescences. This cultivar is frequently cited as one of the most disease resistant in our area. However, it did develop some powdery mildew in the second and third years of the trial, demonstrating just how severely the trial garden was affected. Despite the mild powdery mildew, ‘Robert Poore’ proved to be a sturdy and robust selection with an excellent display of intensely fragrant flowers.
