Growing Conditions

Iris laevigata 'Variegata' thrives in full sun to partial shade and prefers consistently moist or waterlogged soil. It grows well in shallow water up to 10–15 cm (4–6 inches) deep, making it ideal for pond edges, bog gardens, or other wetland areas.

Propagation and Care

Iris laevigata 'Variegata' can be propagated by division or seed. Division is the most effective method and is best performed in early spring or late summer. To propagate, carefully lift the rhizomes, divide them into sections with roots and shoots, and replant them in suitable moist conditions.

Once established, the plant is low-maintenance. Regular watering is essential to maintain its preferred damp environment. Deadheading spent flowers keeps the plant tidy, while cutting back old foliage in late autumn prepares it for winter dormancy and encourages fresh growth in spring.
