Variegated Japanese Water Iris

Variegated Japanese water iris brings striped foliage to pond margins and moist borders, then sends up purple flowers in early to midsummer. Its upright leaves stay ornamental before and after bloom, making it useful even where flowers are brief. ## Site and size Grow in full sun or partial shade with consistently moist soil; it tolerates clay and suits pond edges and bog gardens. Allow room for a clump roughly 18–24 inches wide. Published height estimates vary from about 27 inches to 1 meter, so mature height depends on growing conditions and source. [The RHS profile](https://www.rhs.org.uk/plants/99775/iris-ensata-variegata-v/details) describes striped leaves, deep purple flowers, and moist-site needs, while [Perennials.com](https://www.perennials.com/plants/iris-ensata-variegata.html) lists zones 4–9 and a 27–29-inch height. ## Growing Keep the root zone moist through flowering; plants may take drier soil after bloom, but do not let them dry out for long periods. The grassy leaves form a clump of green and white stripes. Use the flowers for cutting, or place the iris where the foliage can contrast with broad-leaved pond plants. ## Maintenance Remove yellowing leaves in fall or before new growth emerges. Divide established clumps every three to five years, preferably after flowering or in late summer, and replant divisions promptly. Wear gloves when handling and keep plant parts away from children and pets; the RHS lists this iris as harmful if eaten.
