Blue flag iris thrives in consistently moist to wet soil and is ideal for rain gardens, pond edges, or boggy areas. Plant in part shade to full sun and divide clumps every 3-4 years to maintain vigor. Avoid letting roots dry out completely, as this plant naturally grows along stream banks and wetland margins.
