Iris laevigata ‘Rose Queen’ - Marginal Pond Plants - MPP049

Iris laevigata ‘Rose Queen’, commonly known as Rose Queen Japanese Water Iris, is a stunning aquatic perennial that adds elegance and vibrant colour to water gardens, pond margins, and damp borders. This cultivar of Iris laevigata is prized for its striking pinkish-rose flowers and upright, sword-like foliage, making it a standout feature in any moist garden setting.

Description

Iris laevigata ‘Rose Queen’ grows to a height of 60–90 cm (24–36 inches) with a spread of 30–60 cm (12–24 inches). The plant forms dense clumps of narrow, upright leaves that remain an attractive bright green throughout the growing season.

In late spring to early summer (May to July), tall flower stems rise above the foliage, bearing large, delicate blooms in a soft rose-pink hue. The flowers are elegantly shaped, with gracefully spreading falls and slender standards. Each flower is accented with a small yellow signal patch at the base, adding a subtle contrast.

Growing Conditions

Iris laevigata ‘Rose Queen’ thrives in full sun to partial shade and prefers consistently moist or waterlogged soil. It is ideal for planting in shallow water up to 10 cm (4 inches) deep, making it perfect for pond edges, bog gardens, or wetland areas. The plant grows best in rich, slightly acidic to neutral soils, including loam and clay.

Fully hardy in the UK, Rose Queen tolerates frost and regrows vigorously in spring after winter dormancy, making it a reliable choice for temperate climates.

Propagation and Care

Iris laevigata ‘Rose Queen’ can be propagated by division or seed. Division is the most reliable method and is best done in early spring or late summer after flowering. To propagate, lift the rhizomes, divide them into sections with roots and shoots, and replant them in suitable moist conditions.

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