  A well-named, honey-scented, lavender-purple flowering ‘Butterfly Bush’ that differs from typical buddlejas by having downwardly cascading 12-14” (30-35cm) panicles that conjure images of a bursting, bonfire night firework. Pastel-coloured spires make ‘Grand Cascade’ a marvellous back of the border or corner spot backdrop where insects and butterflies will mooch around its honey-scented blooms throughout the summer.
  
  
• Garden care: Prune back hard in March, removing all of the previous year's growth to three or four buds.
