  • Gorgeous large white flowers with creamy yellow lower petals with green veins appear in May and June among slender grassy leaves. Like all Siberian flag irises, this is a clump-forming plant that needs space to spread out and it prefers a moist, neutral to slightly acid soil in sun or partial shade. It looks at its best planted in bold drifts beside water and allowed to naturalise. 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.
