I belong to the Central Arkansas Iris Society (CAIS). It is about a 75 minute drive one way but it is worth it. You can learn so much and it is just great to hear what is going on in a local(ish) community regarding iris gardens. Speakers come in each month and any hybridizers that live in your area are usually members and attend faithfully if their health permits. We have an annual dig and sale each year. We have iris projects that we work to promote AIS, CAIS and growing irises. There are committees that serve either on projects or deciding to buy irises for the projects. I serve on the board of directors but the board only meets four times a year. Otherwise it does take communicating and decision making via emails. We take field trips to big iris growers gardens which are informative and enjoyable.
It is a bit of a drive and it is a bit of work but being with iris people and talking iris is always a great way to spend an afternoon.
I recommend you attend as a guest and see how you like it. As for the sales we sell our extra increases for three and four dollars a healthy rhizome and the dwarfs go for one or two. A lot of our irises are new intros but we have historics too.
