Ming Treasure Ampliflora Iris Plant

Iris amplifora 'Ming Treasure' is one of the largest and most prolific irises! Ming Treasure produces huge 4.5-inch blooms that are a mid violet with a classic yellow crest. This new hybrid is much larger than other irises. Ming Treasure ships as a bare root. We like growing from bare roots because they establish quickly, become twice the size of a potted plant in the first season, and eliminate the need for plastic pots (a win for the environment).

Planting Instructions:

• - Can be planted anytime soil temperatures are above 45°F
• - Plant rhizomes 1-2 inches deep, ensuring the roots are covered with soil but the crown remains slightly above ground level
• - Space plants 12-18 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
• - Performs well in boggy areas or along pond edges where soil stays consistently moist

Watering Specifics:

• - Water deeply at planting to establish roots
• - Keep the soil consistently moist, especially during the growing season
• - Can tolerate standing water, making it suitable for water gardens or wet areas

Fertilizer Type:

• - Apply a balanced fertilizer (10-10-10) in early spring and again after blooming to promote growth
• - Organic options like bone meal or fish emulsion are also effective for sustained nutrition

Pruning and Training:

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

Additional Pest Management:

• - Ampliflora Iris is generally pest-resistant but monitor for snails and slugs in wet conditions
• - Ensure good air circulation to prevent fungal diseases 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
