This perennial dies back to below ground level each year in autumn, then fresh new growth appears again in spring.


  • Position: full sun or partial shade
  • Soil: fertile, moist, well-drained soil
  • Rate of growth: average
  • Flowering period: July to October
  • Hardiness: fully hardy

    A disease-resistant and vibrantly coloured cultivar that produces large domed clusters of white-eyed, hot pink flowers, which open from pointed buds throughout the summer. Plant in bold drifts for maximum impact and make sure you have enough for the vase.

  • Garden care: Support with bamboo canes, brushwood or ring stakes before the flowers appear. Phlox are greedy plants, so apply a mulch 5-7cm (2-3 in) deep of well-rotted garden compost or manure in early spring. Shear off the spent flowers to prevent reseeding. If the leaves show signs of powdery mildew, cut down to the ground and dispose of the affected foliage, but do not compost it. Clear away the debris around the plant to reduce the chances of reinfection. Cut down to the ground in autumn. Lift and divide large clumps in autumn or spring.
