Angel Mountain Japanese Iris

Angel Mountain Japanese Iris (Iris ensata 'Angel Mountain')

Angel Mountain Japanese Iris forms tall, upright clumps of sword-like leaves and produces large, double deep violet blue flowers accented by a clean white center in early to mid summer. It excels in moist, acidic, organically rich soils and is ideal near water features.

Distinctive Features

Bold, ruffled double blooms with striking white centers rise above architectural foliage; thrives in consistently moist sites and delivers stately vertical presence at pond edges and rain garden margins.

• Soil: Moist, acidic, organic rich, well drained soil; tolerates shallow, seasonal wetness in growing season.
• Water: Keep evenly moist; do not allow to dry out, especially in bud and bloom.
• USDA Hardiness Zones: 4 to 9.
• Mature Size: Typically 2.5 to 3 ft tall and 1.5 to 2 ft wide.

Low Maintenance Care

• Watering: Maintain constant moisture; increase during heat and bloom to sustain flower size.
• Pruning: Remove spent stalks after bloom and trim foliage in late fall to tidy clumps.
• Fertilizing: Top-dress with compost in spring; apply an acid-forming fertilizer if soils are neutral.
• Mulching: Apply a 2 inch mulch to conserve moisture and keep roots cool, keeping mulch off crowns.
• Notes: Divide clumps every 3 to 4 years after flowering to maintain vigor and bloom.
