This perennial dies back to below ground level each year in autumn, then fresh new growth appears again in spring.

• Position: full sun or partial shade
• Soil: well-drained soil
• Rate of growth: fast-growing
• Flowering period: June to July
• Hardiness: fully hardy
  
  The showy terminal racemes of pure white pea-like blooms of ‘Polar Princess’ rise above palm-shaped, mid-green foliage, bringing elegantly muted colour, structure, and form to the garden. Flowering in June and July, if paired with the white Chinese wisteria, either as a standard or a climber, you’ll have tumbling and rising racemes for weeks on end!
  
  
• Garden care: Stake with bamboo canes or other natural support in spring before the flowers appear and deadhead the faded blooms to encourage a second flush of flowers. Protect young plants from slug and snail damage, and cover the crown of the plant with organic mulch to insulate from hard frosts.
