SUN PHLOX Phlox paniculata 'Lavelle' «««« Phlox paniculata 'Lavelle' originated in the garden of Jeana Prewitt and is thought to be a seedling of the cultivar 'Jeana'. Although 'Lavelle' is not as disease free as 'Jeana', it still boasts above-average resistance to powdery mildew. ‘Lavelle’ has white flowers with pale pink floral tubes that are held on 4' tall stems. The floral display is one of the longest in the trial, lasting from early July through late August. 'Lavelle' did suffer from being placed next to the sidewalk which reflected a lot of heat and greatly contributed to spider mite infestations. Despite these challenges, 'Lavelle' proved vigorous and resilient and would likely perform even better in a less stressful environment. Phlox paniculata 'Robert Poore' «««« 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 year 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. 5
