About Siberian iris
Iris sibirica, commonly known as Siberian iris, is an elegant perennial plant characterized by its slender stems and delicate flowers in shades of blue, purple, white, or bicolour. Its narrow, upright leaves give it a graceful appearance, making it ideal for pond margins, wetland gardens, or flower beds where a touch of natural sophistication is desired. It blooms in late spring and early summer, bringing vibrant color to the landscape.

Care tips
It prefers full sun to partial shade and moist, well-drained soils rich in organic matter. Keep the substrate consistently moist, especially during flowering, but avoid prolonged waterlogging. A common mistake is planting it in dry soils or those with low organic matter, which can affect its vigor and bloom. Dividing clumps every 3-5 years in autumn or spring will help maintain its vitality.
