This shrub is deciduous so it will lose all its leaves in autumn, then fresh new foliage appears again each spring.

  • Position: full sun
  • Soil: humus-rich, moist but well-drained, neutral to slightly alkaline soil
  • Rate of growth: average to fast-growing
  • Flowering period: August to October
  • Hardiness: fully hardy

    When grown in a sunny spot, this gorgeous, late summer-flowering shrub will produce an abundance of showy white flowers, each with a conspicuous red eye. Its upright habit and attractive foliage makes it a handsome addition to the border.

  • Garden care: To encourage a bushy habit prune young plants hard in late spring. After pruning apply a generous 5-7cm mulch of well-rotted garden compost or manure around the base of the plant. Once established it requires little if any regular pruning.
