‘White Swirl’ is a Siberian iris that features white flowers with yellow throats. Flowers are beardless and ruffled. Mixes well with other perennials in borders. Also effective when planted along a slope or hillside, along a path or along a stream or pond margin. A good moisture-loving plant for moist garden areas. Massed plantings and well-placed specimens can enhance almost any setting, and the foliage provides lasting beauty after bloom. Excellent cut flower, but usually lasts only two days.
