WaterThe Standard Dwarf Bearded Iris, specifically 'Peter James', requires moderate watering. It should be watered deeply to encourage root growth, especially during the growing season. In general, watering once a week with about 1 to 2 gallons is sufficient for established plants, but this may vary depending on climate and soil drainage. During hot, dry periods, increase watering to twice a week. Make sure not to overwater, as this can lead to root rot. After bloom season, you can reduce watering to help the plant harden off for winter.
LightStandard Dwarf Bearded Iris like 'Peter James' thrive best in full sun conditions. They should be planted in a spot where they receive at least six hours of direct sunlight daily. Enough sun is crucial for the irises to bloom prolifically. However, in extremely hot climates, providing some afternoon shade can help protect the flowers from the intensity of the late-day sun.
TemperatureThe Standard Dwarf Bearded Iris 'Peter James' can tolerate a wide range of temperatures but performs best in conditions where temperatures range between 35°F and 75°F. They are cold-hardy and can survive winter temperatures down to -20°F. It is vital to avoid extreme heat above 90°F during the flowering period as high temperatures can affect blooms.
PruningThe Standard Dwarf Bearded Iris 'Peter James' benefits from pruning to promote health and reblooming. After the blooms fade, cut back the flower stalks to the plant's base to prevent energy from going to seed production. In late summer or early fall, trim away dead or damaged leaves. A more thorough cleanup can be done after the first frost to prepare for winter, which also helps to prevent disease.
CleaningAs needed
SoilThe Standard Dwarf Bearded Iris 'Peter James' thrives best in well-draining, loamy soil enriched with compost or humus. The ideal pH range for this iris is neutral to slightly acidic, between 6.8 and 7.0. Amending the soil with bone meal can also encourage strong root development and enhance blooming.
RepottingStandard Dwarf Bearded Iris 'Peter James' typically does not need frequent repotting. It is recommended to divide and replant these irises every 3 to 4 years to maintain vigour and to prevent overcrowding, which can inhibit blooming.
Humidity & MistingStandard Dwarf Bearded Iris 'Peter James' is tolerant of a wide range of humidity conditions and does not require high humidity to thrive. Average ambient humidity is typically sufficient for these irises, avoiding overly wet or swampy conditions that can promote root rot.
Suitable locationsIndoor
Ensure full sun, well-draining soil, and infrequent watering for Standard Dwarf Bearded Iris 'Peter James'.

Life cycleIris 'Peter James', a type of Standard Dwarf Bearded Iris (SDB), begins its life cycle with germination from seed, influenced by soil temperature and moisture levels. Following germination, the seedling emerges and develops into a young plant with characteristic grass-like leaves. Over time, the plant forms a rhizome, which serves as an underground stem for nutrient storage and new growth. The iris reaches maturity and starts the blooming phase in late spring to early summer, producing distinctive flowers in shades of blue, purple, or bi-colors that attract pollinators. After flowering, the plant sets seeds while the foliage continues to photosynthesize and store energy in the rhizome for the next season. Finally, in the dormant stage during late fall and winter, the plant's above-ground growth dies back, but the rhizome survives underground to sprout again in the following spring.
PropogationPropogation time
Spring-Summer
Iris 'Peter James', a variety of Standard Dwarf Bearded Iris (SDB), can be propagated by division, which is the most popular and effective method for this plant. The best time to divide and replant irises is late summer, typically about 4 to 6 weeks after flowering has ended, when the weather has cooled but there is still time before the frost. To propagate by division, carefully dig up the clumps of iris rhizomes after the foliage has begun to die back. Using a sharp knife, divide the rhizomes so that each section has at least one healthy fan of leaves and a portion of the roots. Trim the leaves to about one-third of their height, which is usually about 4 to 6 inches (10 to 15 centimeters), to help prevent water loss and make the plant easier to manage. Replant the divided rhizomes promptly, setting them so the top of the rhizome is just below the surface of the soil while ensuring the roots are well spread out in the planting hole. Water them in well to help establish contact between the roots and the surrounding soil.
