>I want to know if it is possible to induce flowering in louisiana irises >during fall? The only cases I've heard of this occurring were transplanting them from a warm climate to a cold climate during the fall. Established irises will not bloom in fall. With that said, I should point out that some newer cultivars out of Australia are rebloomers. But the vast majority of Louisiana Irises are not rebloomers. You can visit the Iris Haven website and search their list for the word "rebloom" to find a few of those new varieties. http://www.irishaven.com.au/ Dennis in Cincinnati
