Beautiful, pure white flowers with unusual, rounded, flared petals and a yellow base appear in May and June among slender, 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 its 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.
- Harmful if eaten
