Iris fulva, commonly known as Copper Iris, is a perennial herb native to floodplains, marshy areas, and the edges of streams and ponds in the southeastern United States, particularly in Louisiana and Mississippi. It typically grows to a height of 45–80 cm (18–31 in) and features sword-shaped bright green leaves. The Copper Iris is notable for its unique flower colors, ranging from copper-red to deep red, with flowering occurring from April to June. The flowers are slightly fragrant and can also exhibit shades of brick-red, rust-red, bronze, and occasionally yellow. This species is valued for its striking flower colors and ability to thrive in wet conditions.

Copper Iris is often used in water gardens, rain gardens, and naturalized areas due to its affinity for moist environments and its vibrant flowers. It is adaptable to full sun or part shade and prefers acidic soils with high organic content and fertility. Consistent moisture is crucial, especially from autumn to spring, to ensure vigorous growth and flowering. While hardy from USDA Zones 3 to 10, it may flower poorly in regions with cool summers. In containers, Copper Iris requires annual repotting and division. Mulching new plantings can protect against sun-scald, but plants in water gardens do not require mulching and may grow more rapidly. Fertilization should be done before flowering, and care should be taken to avoid overly dense planting, which can lead to issues with rhizome rot.CC BY-SA 4.0
