Siberian Iris, including 'Granny Jean', requires consistent moisture, especially during the growing season. Water deeply once a week, providing about 1 to 1.5 gallons per plant to encourage strong root development. During hot, dry spells, increase watering to twice per week. It's important to avoid overhead watering to minimize the risk of leaf spot diseases; instead, water at the base of the plant. In the winter, reduce watering, as the plant is dormant and requires less moisture.
Siberian Iris 'Granny Jean' thrives best in full sun to partial shade. An ideal spot is one where it can enjoy at least six hours of direct sunlight daily. If planted in too much shade, the iris may not bloom as prolifically. However, in regions with extremely hot summers, some afternoon shade can help protect the plant from scorching.
Siberian Iris 'Granny Jean' is cold hardy and can withstand winter temperatures as low as -40 degrees Fahrenheit. The ideal growing temperatures for this iris are between 50 and 75 degrees Fahrenheit during the growing season. Extreme heat above 90 degrees Fahrenheit can be damaging, so some shade and additional watering may be needed in hotter climates.
Prune Siberian Iris 'Granny Jean' by removing spent flower stalks after blooming to maintain a tidy appearance and to prevent seed production, which can sap energy from the plant. In late fall or early spring, cut back the entire foliage to a few inches above the ground to remove any dead leaves and to reduce the chance of disease. Pruning should be done annually for the best growth and flower production.
Sibirica Iris 'Granny Jean' prefers a well-draining soil mix rich in organic matter. A good mix can be created with equal parts loamy garden soil, peat moss, and coarse sand to ensure proper drainage. The ideal soil pH for this Siberian iris should be slightly acidic to neutral, around pH 6.0 to 7.0.
Siberian Iris 'Granny Jean' usually does not require frequent repotting and can be done every 3 to 5 years. It's best to repot when the clumps become overcrowded or the center of the clump shows signs of dying out, usually in late summer after flowering has finished.
- Humidity & Misting
Siberian Iris 'Granny Jean' is adaptable to a wide range of humidity levels but prefers average garden conditions. No specific humidity level is required as long as the plant has adequate moisture at the roots and good air circulation to prevent disease.
- Suitable locations
Place Sibirica Iris 'Granny Jean' in bright light indoors.
Plant in full sun to part shade with moist soil outdoors.
- Life cycle
The life cycle of the Siberian Iris 'Granny Jean' begins with seed germination, typically in spring, where warmth and moisture encourage the seed to sprout and form a small seedling. This seedling grows into a clump of grass-like foliage, and as the plant matures, it develops a rhizome, which is a horizontal stem that grows underground and stores nutrients. Each year, the Siberian Iris 'Granny Jean' enters a period of active growth in the spring, producing tall, slender stems and elegant flowers that are usually bluish-purple with contrasting markings. After flowering, usually in late spring to early summer, the plant sets seed in a capsule if pollination has occurred. During the summer months, the foliage continues to photosynthesize, providing energy for the next season's growth. As winter approaches, the plant enters dormancy, with the rhizome surviving underground through the cold months, ready to regenerate the next spring.
The Iris 'Granny Jean', commonly known as a type of Siberian Iris, is best propagated by division. The ideal time for dividing these irises is late summer to early fall, after they have finished blooming. To propagate by division, carefully dig up the clumps of Iris 'Granny Jean' and gently separate the rhizomes, ensuring that each division has at least one fan of leaves and healthy roots attached. Trim the leaves to about 6 inches (15.24 cm) to reduce water loss and replant the divisions promptly, setting the rhizome so the top is just below the soil surface in a well-drained spot that receives full to partial sunlight. Water the divisions well to help establish them, ensuring the soil stays moist but not waterlogged as the plants take root.
