The velvety petals of this lush cultivar are glorious shades of rich purple, with pale, creamy-yellow at their base. Their colour works particularly well in bruised colour schemes, so team it with deep reds and purples in a sunny, mixed border for major wow factor.

Garden Care: Plant shallowly with the upper part of the rhizome sitting on the surface of the soil incorporating a low-nitrogen fertiliser in the planting hole. After planting remove the upper-most third of the leaves to minimise the incidence of wind rock. In exposed areas stake with bamboo canes in early spring.
