About Blood red iris
Iris sanguinea, commonly known as Japanese Iris, is a rhizomatous perennial plant admired for its elegant, large, flat flowers that bloom in a wide range of colors, from pure white to deep purple, often with contrasting veins or markings. Its narrow, sword-shaped leaves form attractive upright foliage. It is ideal for pond edges, streams, or moist gardens, adding a touch of oriental sophistication.

Care tips
It requires full sun for optimal flowering and consistently moist, even boggy, soil, especially during the growing season. It prefers an organic-rich substrate, slightly acidic to neutral, with good drainage but moisture retention. Avoid letting the soil dry out completely, as this can stress the plant and reduce flowering.
