✂️ Care

Regularly remove faded flowers to encourage prolonged blooming. A light pruning in late winter removes damaged foliage and rejuvenates the plant. Keep the soil consistently moist, especially during active growth and dry periods.

Little intervention is needed beyond consistent watering and division every three to four years to revitalize clumps.

Iris versicolor is a spectacular perennial ideal for natural-style gardens, mixed borders, wet areas, pond edges, and sunny rain gardens.
