Highly scented, award-winning Wisteria brachybotrys 'Shiro-Kapitan' is a gorgeous climber with flowers of great beauty. It produces masses of hanging sprays, up to 6 in. long (15 cm), of fragrant, pea-like, snow-white flowers with a conspicuous yellow spot. Blooming more or less simultaneously in late spring or early summer as the leaves emerge, they produce a dramatic floral display. The flowers are followed by attractive, velvety, bean-like pods, 8 in. long (20 cm), which ripen in late summer and may persist into winter. Particularly attractive is the dense foliage of exotic-looking, fresh green, pinnate leaves which consist of 11 downy leaflets. 

  • Winner of the prestigious Award of Garden Merit of the Royal Horticultural Society
  • A long-lived climber, this Silky Wisteria can grow vigorously up to 10-40 ft. tall (3-12 m). It climbs by twining anticlockwise (from right to left around the axis). 
  • Thrives in full sun or part shade, in moderately fertile, medium moisture, well-drained soils. Drought tolerant. Best flower production is obtained in full sun.
  • Can be grown against a house wall, arbors, pergolas, trellises, fences, or trained as a free-standing half standard. It must be sited and trained on sturdy structures which will be able to support the heavy weight of the mature Wisteria. Grow this plant around patios where the flowers can be enjoyed.
  • Susceptible to foliage-chewing insects and fungal diseases, but none are significant. Deer resistant
  • Needs regular pruning in order to control the size and shape of the plant and to promote flowering. 
  • Propagate by layering, softwood cuttings, hardwood cuttings, or grafting. Choose sites wisely because plants dislike being transplanted. 
  • All parts may cause severe discomfort if ingested.
