The Mt. Diablo Iris Society annual flower show is a judged exhibition of locally grown iris varieties. Located at the beautiful Alden Lane Nursery in Livermore, we also offer many potted irises for sale. Members of the society will be available to answer your iris questions. If you would like to exhibit an iris in the show, please arrive before 9:00am on April 8 and you will be assisted staging your iris bloom. You do not have to be a member to exhibit. Questions about our event, please phone Mary at 925 606-0355.
