Iris sanguinea ‘Snow Queen’ – Elegant White Iris for Borders and Waterside Planting
Iris sanguinea ‘Snow Queen’ is a graceful hardy perennial, admired for its pristine white flowers and slender upright foliage. Flowering in late spring and early summer, it produces elegant blooms that appear to float above neat clumps of narrow green leaves, bringing freshness and sophistication to the garden.
The pure white flowers create a calming effect and combine beautifully with both vibrant and pastel-coloured planting schemes. Their delicate appearance contrasts wonderfully with the strong vertical foliage, adding texture and structure even when not in bloom.
Unlike many larger iris species, ‘Snow Queen’ forms tidy clumps that fit comfortably into mixed borders, cottage gardens, and naturalistic planting schemes. It is also particularly effective near ponds, streams, and damp areas where its graceful habit can be fully appreciated.
Thriving in full sun or partial shade, it prefers moist, fertile, well-drained soil and benefits from consistent moisture during the growing season. Hardy and reliable, it forms gradually expanding clumps that provide increasing impact year after year.
Elegant, easy to grow, and beautifully understated, Iris sanguinea ‘Snow Queen’ is an excellent choice for adding purity, structure, and seasonal beauty to the garden.
