Iris sanguinea 'Snow Queen', gen.

Upright, clump-forming. Reaches a height of approx. 0.6 - 1.0 m (2-3.3 ft) and spreads about 0.4 - 0.6 m (1.3-2 ft) wide.

Deciduous, narrow, sword-shaped, and an attractive blue-green. They form dense clumps.

Elegant, pure white, flag-like flowers with a golden-yellow throat. They appear profusely from May to July.

Prefers full sun to partial shade.

Very good frost hardiness (down to approx. -29°C, USDA Zone 3). Reliably overwinters outdoors.

Moist to fresh, well-drained, humus-rich, and nutrient-rich soil. Tolerates acidic to neutral soils. Prefers moist but not waterlogged conditions.

Ideal for perennial borders, moist meadows, pond edges, stream banks, and as a cut flower. Also very effective in mass plantings.

Medium to high water requirement. The soil should be kept consistently moist, especially during the blooming period and dry spells.

Very low maintenance. Spent flower stalks can be removed after blooming. Dividing established clumps every few years in late summer/early autumn promotes vigor.

Containerized plants can be planted year-round, except when the ground is frozen. However, the best planting time is spring or autumn.

Iris rhizomes can be poisonous if ingested.
