Fragrant, tubular flowers (1/2" to 1 inch diameter) with long corolla tubes and five flat petal-like lobes. Strong plants and a vigorous grower. 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.

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.
