This perennial dies back to below ground level each year in autumn, then fresh new growth appears again in spring.

  • Position: full sun or partial shade
  • Soil: well-drained, moderately fertile, neutral to slightly acid soil
  • Rate of growth: average
  • Flowering period: May and June
  • Hardiness: fully hardy


    Gorgeous, large, creamy-white flowers with pale yellow falls that have green veining, 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.
  • Harmful if eaten
