  A superb white wisteria with racemes of ivory, pea-like flowers and a heady scent emerging in late spring on woody twining stems. 'Clara Mack' has dark green leaves divided into narrow, lance-shaped leaflets and is less vigorous than the Asian wisterias so perfect for smaller spaces. Raised from a cutting, this wisteria blooms earlier than seed-grown forms.
  
  
• Garden care: Incorporate some well-rotted organic matter and mycorrhizal fungi when planting your Wisteria and keep well-watered until established, particularly in dry summers. Prune in July to reduce the long thin green growth and again in January to further reduce these stems to encourage flower buds.
