Iris x barb. -elat. 'Bianca'

Upright and clump-forming. Typically reaches a height of 0.8 - 1.0 m (2.6-3.3 ft) and spreads about 0.3 - 0.5 m (1-1.6 ft) wide.

Deciduous, sword-shaped, and a beautiful blue-green. They form attractive fans that provide structure in the garden.

Large, showy, pure white flowers with ruffled edges and a prominent white "beard". Blooms appear in late spring to early summer (May to June).

Thrives in full sun (at least 6 hours direct sunlight daily) for optimal flowering. Good air circulation is beneficial.

Very good frost hardiness (USDA Zones 3-9). Reliably overwinters outdoors.

Prefers well-drained, neutral to slightly alkaline soil. Good drainage is crucial; avoid heavy, wet soils. Plant rhizomes just at or slightly above the soil surface.

Excellent for perennial borders, mixed beds, rock gardens, cottage gardens, and as cut flowers. Its striking white blooms create a beautiful contrast with other colors.

Low to medium water requirement. Once established, it is relatively drought-tolerant. Water during prolonged dry spells, especially during bloom, but ensure good drainage.

Generally low maintenance. Remove spent flower stalks after blooming. Divide overcrowded clumps every 3-5 years in late summer (July-September in your location in Ketzin) to maintain vigor and flowering. Remove any yellow or diseased leaves.

Best planted in late summer to early autumn (July-September) in your region, allowing roots to establish before winter. Can also be planted in spring, but autumn planting is often preferred.

The rhizomes of Irises can be toxic if ingested.
