✂️ Care

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

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

Iris laevigata 'Tiramisu Dinner Plate' is a spectacular perennial ideal for natural-style gardens, mixed borders, moist areas, and sunny to partially shaded areas.
