Water
The Siberian Iris prefers consistent moisture and should be watered deeply once a week, providing approximately one inch of water each time. During hot or dry spells, increase watering frequency to maintain soil moisture. It's vital to avoid overwatering, as this can lead to root rot. Ensure that the soil drains well to prevent water from pooling around the roots. In terms of the amount, over a month during the growing season, you might apply about four gallons per plant, adjusting as necessary for rainfall and temperature conditions.
Light
Siberian Iris thrives in full sun to partial shade, with at least six hours of direct sunlight daily. An ideal spot is one where morning sun dapples through, offering protection from the harsh afternoon sun. These conditions will encourage the robust growth and best blooming potential of the iris.
Temperature
The Siberian Iris is hardy and can tolerate winter temperatures as low as -30 degrees Fahrenheit. The ideal growing conditions for the Siberian Iris are within the range of 68 to 85 degrees Fahrenheit during the growing season. However, they are quite adaptable and can survive summer highs up to 90 degrees Fahrenheit.
Pruning
Pruning Siberian Iris involves removing spent flower stems after blooming to maintain plant appearance and prevent seed formation. In late fall, cut the foliage down to a few inches above the ground to tidy the plant and discourage overwintering pests and diseases. Pruning is typically done annually, and the best time for cutting back foliage is after the first hard frost.
Cleaning
As needed
Soil
Siberian Iris prefers moist, well-drained soil that is rich in organic matter. A good soil mix for Siberian Iris would consist of loamy garden soil, compost, and peat or leaf mold to improve water retention and soil structure. The ideal soil pH for Siberian Iris is slightly acidic to neutral, ranging from 6.0 to 7.0.
Repotting
Siberian Iris typically does not need to be repotted frequently; it should be divided and repotted every 3 to 5 years to prevent overcrowding and to maintain plant vigor. Repot in late summer after blooming has finished or in early spring before growth starts.
Humidity & Misting
Siberian Iris is quite adaptable and does not require specific humidity conditions. It grows well in outdoor garden settings where it receives natural ambient humidity without the need for additional misting or humidity regulation.
Suitable locations
- Indoor
  Ensure bright light but avoid direct sun.

Life cycle
The Siberian Iris 'White Swirl' begins its life cycle as a seed, usually sown in the fall to allow for a period of cold stratification which is crucial for germination. After a winter dormancy, seeds germinate in the spring as temperatures warm, and sprouts emerge from the soil, developing into young plants. As the young Siberian irises establish themselves, they form clumps with distinctive grass-like leaves and begin to take up nutrients and water, maturing through the spring and early summer. The flowering stage occurs in late spring to early summer, when 'White Swirl' produces its characteristic white flowers with a swirly pattern, attracting pollinators for sexual reproduction. After pollination, flowers give way to seed pods that ripen over the summer, eventually drying and releasing seeds to begin the next generation. Throughout the active growing seasons, the Siberian Iris will go through perennial cycles of growth and bloom, while in winter, the plant enters a dormant phase to survive colder temperatures, completing its annual life cycle.
Propogation
- Propogation time
  Late Summer-Early Fall
- The most popular method of propagating Iris 'White Swirl', commonly known as Siberian iris, is by division. This is typically done in late summer after the blooming period, although it can also be done in early spring before growth begins. To propagate by division, you would carefully dig up the entire clump of the iris, ensuring you have a good portion of the rhizome and roots. Using a sharp knife, you would then cut the rhizome into sections, making sure each section has at least one fan of leaves and a portion of healthy roots. These sections are then replanted into the soil at the same depth they were previously growing, and watered well to help establish the plant.
