Phlox
Garden phlox carries full, domed clusters of five-petalled florets in soft pastels and vivid pinks atop tall leafy stems, releasing a sweet summer fragrance. Florists use it as a fragrant, generous filler that fills space and adds cottage-garden softness to seasonal bouquets and arrangements. It sits between a filler and a focal, giving mass without stiffness. Because its foliage spoils water quickly, clean stripping and frequent water changes keep it at its best.
