Shiryukyo Pseudata Iris Plant

Pseudata Iris 'Shiryukyo' is a stunning hybrid iris, combining the best traits of Iris pseudacorus and Iris ensata. This water-loving iris produces large, showy flowers in a captivating shade of violet-blue with yellow signals. The blooms, typically appearing in late spring to early summer, sit atop tall, sturdy stems that can reach 3-4 feet in height. Its sword-like foliage remains attractive throughout the growing season, providing vertical interest even when not in bloom. Shiryukyo thrives in moist to wet soils, making it an excellent choice for water gardens, pond edges, or consistently damp areas of the garden. Like other water irises, it's also effective in helping to filter water in natural water features. This iris is relatively low-maintenance, deer-resistant, and attracts pollinators, combining beauty with practical benefits in the landscape.

Planting Instructions:

• - Can be planted anytime soil temperatures are above 45°F
• - Plant rhizomes 1-2 inches deep, ensuring the crown is just at or slightly above soil level
• - Space plants 18-24 inches apart to allow proper air circulation
• - Choose a location with full sun to partial shade

Soil Preparation:

• - Ideal soil pH: 5.5-7.0, thrives in moist, fertile, well-drained soil
• - Enrich soil with organic matter, such as compost or aged manure, to improve fertility and water retention
• - Suitable for boggy areas, wet soils, or edges of ponds and water gardens

Watering Specifics:

• - Water deeply at planting to establish roots
• - Keep the soil consistently moist; Pseudata Iris thrives in wet conditions and tolerates standing water
• - Reduce watering slightly during dormancy in colder seasons

Fertilizer Type:

• - Apply a balanced fertilizer (10-10-10) in early spring and again after blooming to encourage healthy growth and flowering
• - Organic fertilizers like fish emulsion or bone meal are also effective

Pruning and Training:

• - Remove spent flower stalks to prevent seed formation and keep the plant tidy
• - Trim foliage back to 4-6 inches in late fall to minimize pest and disease risks
• - Divide rhizomes every 3-5 years in early fall to rejuvenate growth and prevent overcrowding

Additional Pest Management:

• - Pseudata Iris is highly pest-resistant but monitor for slugs and snails in wet conditions
• - Ensure good air circulation to prevent fungal issues, especially in humid climates

Temperature Tolerance:

• - Hardy and tolerates a wide range of temperatures
• - Provide mulch in winter to protect the root zone in colder climates, particularly where harsh frosts are common
