Summary

Iris virginica, commonly known as Virginia Iris, is a perennial herb native to wetlands, marshes, and along the edges of ponds and streams in eastern and central North America. It is often found in the coastal plain but also extends to the Great Lakes region. This species typically grows to a height of 30–90 cm (12–35 in) and features slightly fragrant flowers that bloom from April to May. The flowers, measuring 4 cm (1.5 in) long and 7 cm (2.75 in) across, display a range of colors from dark violet to pinkish-white, with 3 horizontal sepals, or "falls," and 3 erect petals. The blooming stalk is erect, sometimes branched, and can have a slight zigzag appearance, bearing 2 to 6 flowers.

Virginia Iris is valued for its showy flowers and ability to thrive in wet conditions, making it ideal for water gardens, rain gardens, and naturalized areas. It is also used for erosion control along waterways. In cultivation, it requires full sun to part shade and prefers consistently moist to wet soils with medium to slow drainage. While it is adaptable to various soil types, it flourishes in rich, acidic soils. Gardeners should be aware that although it is not typically prone to serious pest or disease problems, it can suffer from iris borer, root rot, and rust.CC BY-SA 4.0
