• Spread: 45–60 cm (18–24 inches)

Growing Conditions

Iris kaempferi 'White Lady' thrives in consistently moist to wet conditions and prefers sunny to partially shaded locations.

• Soil: Prefers rich, acidic to neutral soil with excellent moisture retention. Loamy or clay soils enriched with organic matter are ideal for optimal growth.
• Water: Requires consistently moist soil or shallow standing water (up to 10 cm / 4 inches deep) during the growing season.
• Light: Grows best in full sun but tolerates partial shade, particularly in warmer climates. Full sun promotes the most abundant flowering.

This iris is hardy in temperate climates, including the UK, and tolerates frost well.

Propagation and Care

• Division: Divide clumps every 3–4 years in early spring or late summer to maintain vigor and encourage flowering. Replant divisions in freshly prepared, moist soil.
• Seed: While propagation by seed is possible, it is not recommended for cultivars, as seedlings may not retain the unique characteristics of the parent plant.
• Routine Care:
  • Water regularly to ensure consistently moist soil, especially during dry periods.
  • Fertilize in early spring and after flowering with a balanced fertilizer to promote strong growth and vibrant blooms.
  • Deadhead spent flowers to tidy the plant and prolong the blooming period.
  • Cut back foliage to ground level in late autumn to prepare the plant for winter dormancy.

Uses

1. Water Gardens: Thrives near ponds, streams, or in boggy areas, where its moisture needs are fully met.
2. Borders: Adds an air of elegance and height to damp or moisture-retentive borders, creating a stunning focal point.
3. Naturalized Planting: Perfect for naturalizing in wetland areas or along water margins, contributing to a tranquil garden display.
4. Cut Flowers: The pristine white blooms make a sophisticated addition to floral arrangements, adding grace and charm.

Ecological Value

• Pollinators: The nectar-rich flowers attract bees, butterflies, and other pollinators, supporting biodiversity during the blooming season.
• Erosion Control: The dense root system stabilizes soil in wet or waterlogged areas, reducing erosion and improving water retention.

Considerations

• Moisture Needs: Requires consistently moist or wet soil for healthy growth and flowering. Avoid planting in dry or well-drained areas.
• Space Requirements: Allow adequate space for the plant’s upright growth and spreading rhizomes.
• Winter Protection: Though hardy, applying a layer of mulch around the base in colder climates can help protect rhizomes during harsh winters.
