Plant Information

Plant Care

White Swirl Siberian Iris is remarkably low-maintenance once established. Remove spent blooms to encourage a neat appearance and prevent self-seeding. Cut back foliage in late fall to about 4 inches above ground level. Divide clumps every 3-4 years in early spring or fall to maintain vigor and prevent overcrowding.

Regular watering is essential during the first growing season to establish a deep root system. Once established, these iris are drought-tolerant but perform best with consistent moisture. Apply a balanced fertilizer in early spring when new growth emerges.

Planting Instructions

Plant White Swirl Siberian Iris in spring or fall, spacing plants 18-24 inches apart. Dig a hole twice as wide as the root ball and at the same depth. Position the rhizome just below soil level, spreading roots outward. Backfill with soil, firm gently, and water thoroughly.

For container-grown plants, maintain the same planting depth as in the nursery pot. Add organic matter to heavy clay soils to improve drainage. Apply a 2-inch layer of mulch around plants, keeping it away from the crown to prevent rot.
