Bloom All Summer ‘Blue Boy’ is as close to real blue as we’ve seen in Phlox. Tightly packed clusters of bluish-mauve flowers, each with a soft-white star-shaped center. Prune back a third in early spring for a bushier plant with many heads. For large flowerheads prune all but a few large stems on each plant. Also does well in some shade. Garden phlox is a staple of the perennial border. Phlox “paniculata” have large fragrant flowers in large, dense pyramidal clusters. Provides unsurpassed flowering in summer, clear crisp colors and flowers in profusion. Phlox are showy, clump-forming perennials that are easy to grow and look spectacular in borders or mass plantings. Best grown in well-drained soil. Mixes well with other perennials and provides long summer bloom. Regardless of flower color, garden phlox is attractive to hummingbirds and is a good selection for inclusion in a bird garden. Remove flowers when faded. Lift and divide every three or four years to prevent crowding. Good fresh cut flower. Great in borders, rock gardens, formal beds and meadows. Growing to only 20 inches, this phlox can handle pathway traffic and can stand upright in the front border. A great choice for summer cuts and native plant gardens.
