Although the common name is usually referred to as "iris," the term also is the scientific name for over 300 flowers, most of which are part of the Iris genus. This genus includes the following six subgenera:
-Subgenus Iris (bearded rhizomatous irises)
-Subgenus Limniris (bearded rhizomatous irises)
-Subgenus Xiphium (smooth-bulbed bulbous irises)
-Subgenus Nepalensis (bulbous irises)
-Subgenus Scorpiris (smooth-bulbed bulbous irises)
-Subgenus Hermodactyloides (reticulate-bulbed bulbous irises)
Although all irises are commonly seen in both home gardens and larger botanical gardens, certain varieties have grown especially popular. The bearded German iris, a hybridogenic species, is the most common type of iris used in home gardens. Other popular varieties include the Siberian iris, the Japanese iris, the rabbitear iris and the blood iris.
Follow these steps to plant a beautiful and healthy iris:
- Work fertilizer into the soil at least 2 weeks before you begin planting
- Irises should be planted 1-2 feet apart. Don't plant the flowers too deep in the soil.
- Do not overwater. In most climates, rainwater will be sufficient.
