Phlox “Moody Blue” are herbaceous plants that bear a profusion of small, often scented flowers in summer. In the wild, Phlox paniculata can grow to nearly 2m, and typically bears pink flowers. Years of breeding have resulted in shorter, more garden-worthy cultivars that flower in a variety of different colours, including shades of blue, purple, pink, magenta, red and white. As well as being fragrant and long-flowering, most cultivars attract a variety of bees and other pollinating insects. They make excellent cut flowers. For a more contemporary look, combine them with ornamental grasses.
