Buy Phlox paniculata 'Roberta' perennial phlox: A summer showstopper

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, well-drained soil
  • Rate of growth: average
  • Flowering period: July to September
  • Hardiness: fully hardy

    From midsummer to the middle of autumn, large domed clusters of fragrant, magenta-pink flowers appear above the mound of attractive foliage. The colour of these showy flowerheads really stands out in herbaceous borders, where they look sublime mixed with rich purples and softer pinks.

  • Garden care: Support with bamboo canes, brushwood or ring stakes before the flowers appear. Phlox are greedy plants, so apply a mulch 5-7cm (2-3in) deep of well-rotted garden compost or manure in early spring. Shear off the spent flowers to prevent reseeding. Cut down to the ground in autumn, and lift and divide large clumps in autumn or spring.
