Iris pseudacorus variegata, commonly known as the Variegated Yellow Flag, is a striking cultivar of the Yellow Flag Iris that features beautiful variegated foliage alongside the traditional bright yellow flowers. This cultivar adds a touch of elegance and contrast to water gardens, ponds, and bog gardens, making it a visually appealing choice for moist or aquatic settings.

Description

Iris pseudacorus variegata grows to a height of 60–90 cm (24–36 inches), forming an upright, fan-shaped clump of long, sword-like leaves. What makes this cultivar stand out is the variegation on the leaves. The deep green foliage is marked with creamy white or pale yellow stripes that run vertically along the length of the leaves, creating a striking contrast. This variegated foliage provides year-round interest, even when the plant is not in bloom.

The flowers of Iris pseudacorus variegata are large and bright yellow, typical of the Yellow Flag Iris. The flowers have three upright standards and three drooping falls, and they bloom in late spring to early summer, usually from May to June. The falls of the flowers often have a subtle ruffled edge, adding texture to the blooms. The bright yellow flowers attract pollinators like bees and butterflies, making this iris an excellent choice for wildlife-friendly gardens.

Growing Conditions

Iris pseudacorus variegata thrives in full sun to partial shade and prefers moist, consistently wet soil. It is perfect for planting along pond edges, in bog gardens, or in shallow water up to 30 cm (12 inches) deep. This cultivar can tolerate waterlogged soil, making it an excellent choice for aquatic environments or areas with consistently damp conditions. Hardy in UK conditions, Iris pseudacorus variegata is frost-resistant and can survive through winter, reemerging in the spring.

Propagation and Care

Propagation of Iris pseudacorus variegata is typically done by dividing the rhizomes in late summer or early spring. The plant benefits from division every two to three years to maintain healthy growth and encourage continued blooming. Once established, it is low-maintenance but may require occasional thinning to prevent overcrowding. Deadheading spent flowers can help promote new blooms and maintain the plant’s tidy appearance. Regular division helps control the spread of this cultivar and keeps it in check, particularly in smaller garden spaces.

Uses

Iris pseudacorus variegata is ideal for ornamental water gardens, pond edges, and bog gardens. Its vibrant yellow flowers and attractive variegated foliage make it an eye-catching focal point in any damp or aquatic landscape. This cultivar can be planted as a specimen plant, in groups, or as part of a mixed planting scheme in wetland environments. It adds contrast and texture to garden spaces, and its flowers attract pollinators, making it a valuable addition to wildlife gardens.

Ecological Value

Iris pseudacorus variegata offers ecological benefits by stabilising soil along water margins, preventing erosion, and providing habitat for small creatures in aquatic environments. The plant’s nectar-rich flowers support early-season pollinators such as bees and butterflies, contributing to the overall biodiversity of the garden. The ability to thrive in wet, waterlogged conditions also makes this cultivar valuable in wetland restoration projects or water feature designs.

Considerations

While Iris pseudacorus variegata is beautiful and hardy, it can spread rapidly through its rhizomes, similar to the standard Yellow Flag Iris. Regular division is necessary to maintain its size and prevent it from becoming invasive, especially in smaller spaces. It's also important to consider its spread in naturalized areas, as Iris pseudacorus species can be invasive in some regions.

With its bold, variegated foliage and vibrant yellow flowers, Iris pseudacorus variegata is an excellent choice for adding colour, texture, and ecological value to any water garden, pond edge, or bog garden. Its beautiful foliage and flowers, combined with its ability to thrive in wet conditions, make it a valuable and attractive addition to aquatic landscapes.
