Flatter flowers that open wide on this pure-white Siberian iris with golden-yellow throats - deservedly popular with iris enthusiasts and a good doer Val Bourne - Garden Writer

Plant description

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, 'White Swirl' is a clump-forming plant that prefers not to be over-crowded. It's happiest in soils that are reliably moist, with a neutral to slightly acid pH, however it can also tolerate drier conditions. It looks wonderful when planted in bold drifts through borders or beside water, while its naturally spreading habit makes it particularly useful for stabilising banks which are susceptible to erosion.

How to care for Iris White Swirl:

Please note:

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