Sun or partial shade. To one metre +. Fertile humus rich, well drained soil. Smothered in showy clusters of pure white, sweet pea-like flowers among grey-green leaves. A vigorous 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. No fragrance. Cut back the plant to ground level in early spring. 30 seeds (2017)
