The Phlox paniculata is a perennial herbaceous flower that can reach up to 150 cm in height, making it a bright and fragrant addition to landscape designs. These flowers are beloved by flower growers, florists, and landscape designers for their rich palette of colors and various varieties. The flower got its name in Greece, where it was associated with a flame. This is because the "precursors" of modern phlox were distinguished by a bright red color.
Over the years, through hybridization and selection, new varieties of Phlox paniculata with unexpected flower forms and shades have been cultivated (and are still being cultivated). However, there are no yellow varieties yet. A powerful root system ensures the longevity of the plant, allowing it to adorn the garden for years. The flowering time of each flower is 7 days.
