Campanula glomerata var. alba 'Schneekrone'

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, moist, well-drained, neutral to alkaline soil
• Rate of growth: fast-growing
• Flowering period: May to July
• Hardiness: fully hardy
  
  From early to midsummer, the leafy, upright stems of this fast growing perennial are topped with densely packed clusters of bell-shaped flowers. If dead-headed promptly there may be a smaller, second flush.
  
  
• Garden care: Protect the tender foliage from slug damage using environmentally-friendly slug pellets or beer traps. During the growing season water freely and apply a balanced liquid fertiliser each month. Cut back after flowering both to prevent self-seeding and to encourage a second flush of flowers.
