About Us

The Mt. Diablo Iris Society was founded in 1965 and is dedicated to promoting the culture, propagation, and enjoyment of iris plants in the Mt. Diablo region of Contra Costa County. As part of American Iris Society Region 14, we bring together gardeners, hybridizers, and enthusiasts who share a passion for these remarkable flowers.

Our society is committed to educating the public about irises through meetings, shows, sales, and community events. We support iris research, conservation, and the development of new varieties that thrive in our local climate.
