Welcome, iris enthusiasts, to Region 20 of the American Iris Society in Colorado! We are a nonprofit organization that promotes the appreciation and culture of irises. Members receive two local newsletters and four national bulletins - with iris photos and articles on how to grow and where to get them. There's more: iris shows, plant sales, informative meetings, garden tours, and national conventions.

Check our events schedule for details about upcoming programs and activities.

The Mountains and Plains Iris Society will hold its fall meeting on Sunday October 11th in Gates Hall at the Denver Botanic Gardens, starting at 12:00 noon with a potluck luncheon. See the events page for full details.

Find a list of publications about irises and recent newsletters in the Library. Recent newsletters are available online for downloading.
