✂️ Care

Regularly remove spent flowers to encourage prolonged blooming. Light pruning in late winter removes damaged foliage and rejuvenates the plant. Keep the soil consistently moist during the growing season, especially in summer.

Few interventions are needed beyond regular watering and dividing every three to four years to revitalize clumps.

Iris pseudacorus 'Sun Cascade' is a spectacular perennial ideal for natural-style gardens, wet borders, and sunny areas.
