  A classic of the cottage garden, this tall bellflower produces large, white cup-shaped flowers on slender stems in June and July among toothed, bright green leaves, which it retains all year. It's an ideal plant for the back of a mixed or herbaceous border, especially in partial shade. It's earlier flowering than many other varieties, and provides excellent cut-flowers, too.
  
  
• Garden care: Protect the tender foliage from slugs and deadhead regularly. Apply a generous 5-7cm (2-3in) mulch of well-rotted compost around the base of the plant in spring. Stake with bamboo canes or brushwood in spring before the flowers appear. Deadhead to prolong flowering
