Propagation of Iris tenax Dougl. ex Lindl. var. gormanii (Piper) R.C. Foster
Iris tenax Dougl. ex Lindl. var. gormanii (Piper) R.C. Foster, commonly known as Gorman's Iris, is a species of flowering plant in the family Iridaceae. It is native to western North America and is typically found in meadows and forests.
Seed Propagation
One common method to propagate Gorman's Iris is through seed propagation. Seeds should be collected when they are ripe, usually in late summer or early fall. After collecting, they should be cleaned and stored in a cool, dry place until the following spring. In order to increase the chances of germination, the seeds can be stratified by placing them in a moist medium at a temperature of 40°F to 45°F for approximately 60 days before sowing.
When sowing, the seeds should be planted in a well-draining soil mix and covered with a thin layer of soil. The container should then be kept moist and placed in a warm, sunny location. Germination can take anywhere from several weeks to several months. Once the seedlings have emerged and grown to a reasonable size, they can be transplanted into individual containers or directly into the ground.
Division
Another common method for propagating Gorman's Iris is through division. This method is best done in the fall after the plant has finished flowering and the foliage has begun to die back. The plant should be dug up carefully, taking care not to damage the roots. The roots should then be gently separated into individual sections, each containing a small section of the rhizome and some foliage.
These sections can then be replanted immediately in a well-draining soil mix. The new plants should be watered thoroughly and placed in a partially shaded area until they have become established. Once the new plants have grown to a reasonable size, they can be transplanted to their permanent location in the garden.
