  A neat, low-growing verbena producing lax clusters of fragrant, bright purple or magenta flowers from June to September. This jewel-like perennial is perfect for a sheltered, sunny, well-drained spot. Associating well with grey and silver-leaved plants, it's wonderful used in generous drifts for infilling a traditional knot garden.
  

• Garden care: In areas prone to frost apply a deep, dry winter mulch around the crown of the plant.
