Iris laevigata P9
Iris laevigata, commonly known as Japanese water iris, is a graceful, moisture-loving perennial valued for its elegant blooms and slender, sword-like green foliage. This species thrives in wet soils and is ideal for planting at the edge of ponds, streams, or in bog gardens. Its striking flowers—typically in shades of blue to violet—appear in early summer and add a refined, ornamental presence to water-themed or naturalistic garden settings. Unlike some irises, Iris laevigata will grow directly in shallow water, making it a standout in aquatic designs.
