  This robust and undemanding perennial produces magnificent spires of creamy white, pea-like flowers, which look beautiful with fresh greens, whites and blues. A star plant in our Chelsea Flower Show garden in 2014, where Luciano Giubbilei used it in drfits throughout the borders.
  
  
• Garden care: Stake with bamboo canes in spring before the flowers appear and deadhead the faded blooms to encourage a second flush of flowers.
