  Ever popular, this plant is smothered in showy clusters of pure white, sweet pea-like flowers from June to September among grey-green leaves. A vigorous, perennial climber, it looks lovely scrambling over a sunny wall or through a hedge or evergreen shrub, although initially it needs to be tied into supports. Unlike the annual sweet pea, it has no fragrance.
  
  
• Garden care: Incorporate lots of well-rotted organic matter in the planting hole. Pinch out the shoot tips to encourage bushy growth and tie in new shoots to a support. It will self-seed but not necessarily come true, so it is best to deadhead any pods. Cut back the plant to ground level in early spring.
