    Intense violet flowers with speckled and striped markings on the throats appear in June and July among bright green strappy leaves. Like all Siberian flag irises this is a clump-forming plant that needs space to spread out and prefers a moist neutral to slightly acid soil in sun or partial shade. It looks best planted in bold drifts beside water and allowed to naturalise and is particularly useful on difficult banks where it will help to prevent erosion and over time will form large clumps. It can also be planted in a pot as a marginal plant for a pond.

  • Garden care: Plant in soil that has been improved with well-rotted manure or garden compost and do not allow to dry out particularly as the plant is getting established. If planted in a container it will need dividing and repotting every couple of years in spring.
