Iris sibirica 'Snow Crest'

Upright, clump-forming. Typically reaches a height of approx. 0.8 - 1.0 m (2.6-3.3 ft) and spreads about 0.5 - 0.6 m (1.6-2 ft) wide.

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

Elegant, pure white, beardless flowers with a delicate yellow marking at the base of the falls. Blooms appear from May to July.

Prefers full sun to partial shade.

Very good frost hardiness (down to approx. -28°C, USDA Zone 5). Reliably overwinters outdoors.

Moist to fresh, well-drained, humus-rich, and nutrient-rich soil. Tolerates acidic to neutral soils. Good drainage is essential; avoid waterlogging.

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. Established plants can tolerate drier conditions better.

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

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.
