Growth Stages

1

Dormancy/Establishment

4-8 weeks

Rhizomes are planted with minimal foliage. New roots develop and fan growth begins.

Plant in fall (August-September) or early spring. Ensure excellent drainage. Avoid burying rhizomes. Water lightly until established.

2

Vegetative Growth

12-16 weeks

Iris fan develops with sword-like green leaves growing upright. Plants establish multiple shoots from rhizome.

Divide established clumps every 3-4 years after blooming. Apply balanced low-nitrogen fertilizer in spring. Remove dead foliage in late winter.

3

Flower Bud Formation

2-3 weeks

Flower stems emerge from the leaf fan. Buds form along the stem in typical bearded iris arrangement.

Apply bloom-boosting fertilizer (higher phosphorus) when flower stems emerge. Ensure adequate sunlight. Stake tall stems in windy areas.

4

Blooming

3-4 weeks (spring); 2-3 weeks (fall rebloom)

Distinctive white and purple-blue flowers open sequentially on stem. Each flower lasts 1-2 days; stem blooms for 2-3 weeks. 'Stepping Out' typically reblooms in late summer/fall.

Deadhead spent flowers to encourage additional blooms. Remove entire flower stems after all blooms fade. Provide afternoon shade in hot climates to extend bloom color.

5

Post-Bloom Dormancy

4-8 weeks until summer dormancy

Plant focuses energy on rhizome development and nutrient storage. Foliage may yellow or die back partially.

Reduce watering significantly. Allow foliage to remain until it naturally dies back (photosynthesize). Clean up debris to prevent pest issues. No fertilizer needed.
