Wave Action Japanese Iris

Wave Action Japanese Iris (Iris ensata 'Wave Action')

Wave Action Japanese Iris forms upright clumps of sword-like foliage and produces large, near-white to pale blue flowers brushed and veined light blue with a clear yellow center in early to mid summer. It excels in moist, acidic, organic-rich soils and shines at water margins.

Distinctive Features

Broad, flat-petaled blooms show elegant pale blue washes and fine veining that frame a vivid yellow signal; clean vertical foliage provides stately presence before and after bloom.

Growing Conditions

• Sun Exposure: Full sun to partial shade; provide afternoon shade in hotter climates.
• Soil: Moist, acidic, well drained yet humus-rich; tolerates shallow seasonal wetness during growth.
• Water: Keep evenly moist; do not allow to dry out in bud and bloom.
• USDA Hardiness Zones: 4 to 9.
• Mature Size: About 2.5 to 3 ft tall and 1.5 to 2 ft wide.

Low Maintenance Care

• Pruning: Remove spent stalks after flowering; tidy foliage in late fall.
• Fertilizing: Top-dress with compost in spring; use an acid-forming fertilizer if soils are neutral.
