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

• Position: full sun
• Soil: fertile, well-drained soil
• Rate of growth: average
• Flowering period: May to October
• Hardiness: fully hardy
  
  Incredibly long-flowering and prolific, this new cultivar is just as reliable as the much-loved species, but it has slightly larger, lavender coloured flowers. A must-have plant for a sunny spot with freely draining soils, it will soon form a spreading carpet of colour that will last from May to October - if not even longer!
  
  
• Garden care: Trouble free. Avoid excessive winter wet and trim lanky stems in autumn.
