Phlox divaricata 'Blue Moon'

Phlox-Woodland, Wild Sweet William

Selected by wildflower expert Bill Cullina for its compact habit and fragrant, lavender blue flowers. Easy to have in bloom for early spring sales. Cheerful blossoms are borne in large clusters above the semi-evergreen, slowly spreading foliage. Best as a woodland groundcover as it mingles its way through the shade border.

Grower Information

  • Take care not to plant too deeply
  • Best in 1-gal containers
  • Moist, well-drained soil with a 6-6.5 pH
  • Pinch plants prior to or shortly after planting
  • Follow an average watering regime
  • PGR rates to achieve sufficient control are higher on Phlox; begin applications early in the crop cycle

Pot in late summer for highest quality finished plants the following spring. Since the foliage is somewhat evergreen, growing in a cold frame under white poly is better than growing under clear cover. Hold plants cool in winter to avoid premature flowering.
