The Story
Plant Bio
Siberian Irises are beardless irises known for their graceful, slender foliage and delicate, butterfly-like flowers. They form dense, grass-like clumps and are more tolerant of moist soils than bearded irises. 'Victoria Falls' is a reblooming Siberian iris, prized for its large, ruffled, light blue flowers with a distinctive white and yellow signal on the falls. It often produces a second flush of blooms later in the summer.

Planting
How to Grow
- Choose a site in full sun or light shade with moist, acidic soil.
- Amend the soil with compost to improve moisture retention.
- Dig a hole and plant the rhizome 1-2 inches below the soil surface.
- Space plants about 24 inches apart to allow for clump expansion.
- Water thoroughly after planting and keep consistently moist.
- Mulch to conserve water and suppress weeds.
Pro Tip
Unlike bearded iris, plant Siberian iris rhizomes 1-2 inches deep and keep them consistently moist, especially the first year.
Keep It Thriving
Care Guide
Do
- Provide consistent moisture, especially during bloom.
- Plant in slightly acidic soil for best performance.
- Divide every 4-5 years when the center of the clump becomes bare.
- Deadhead spent flowers to encourage a potential rebloom.
Don't
- Do not let the soil dry out completely.
- Do not plant the rhizomes exposed like bearded iris.
- Avoid using lime, as they prefer acidic conditions.
- Do not plant in deep shade, which will reduce flowering.
