The Giant Hardy Phlox Mix, 'Phlox paniculata', have colors that sing in perfect harmony, so you can plant them together in a bright chorus of summer- long bloom, or disperse them among other border perennials. Majestic, fragrant favorites for the summer border! These choice hybrids are among the finest Garden n Phlox available today. They bloom prolifically all summer - starting earlier than Grandmother's garden Phlox - with strong colors that won't fade. The large vibrant flower clusters are lovely in vases and fragrant, too! The deep green lance-shaped leaves climb the strong stems and create a dense, compact clump that is attractive even when not in bloom. Plant Phlox liberally toward the back of the perennial border, spacing them 18" apart in humus-rich, well-drained soil. Divide every 2-3 years. Height: 24-36".
