Very variable but none the less very handsome this beardless iris looks wonderful when planted in bold drifts through the border. With a maximum height of 90cm they can also be lower growing, sometimes considerably so. The flowers come in shades of blue or purple-blue and the mid green leaves often have a red flush at their bases.

  • 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.
