Purple petals make up the flowers of this delightful Siberian iris. This will create an impact almost immediately. Plant in bold swathes throughout the border, where its upright form will add vertical interest in early summer.

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.
