In cultivation since the 1800s, phlox are historic perennials and beloved garden performers. Many phlox species are native to the eastern United States, and resilient varieties span the genus. Some enjoy sunny garden locations, while others are woodland species and benefit from partial afternoon shade.
These blooming perennials bring high color in spring through fall on upright or spreading stems, depending on the variety. Powdery mildew is a common issue among the group, exacerbated by high humidity and heat. The fungal disease may cause little damage and is mostly unsightly. In severe cases, it causes stress and leads to defoliation and decline. Thankfully, disease-resistant cultivars are available and covered in this article.
Phlox grows best in organically rich, moist, and well-drained soils. To support overall health, it’s best to provide plenty of air circulation, appropriate sunlight conditions, and irrigate from the base. Whether spring or summer bloomers, tall or low, these pollinator favorites delight with rich hues and a sweet fragrance. Phlox, from the Greek for “flame,” boasts an eye-catching floral display.
