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 iris, 'Butter and Sugar' 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.
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.

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 grown in a container, it will need dividing and repotting every couple of years in spring.
Remove the stems after flowering from the base as this will concentrate the plant's energy into producing new rhizomes. Divide and replant about every three years.
