The Iris Society of Massachusetts (ISM) is friendly, exciting, sociable and educational. We are a group of people who love irises of all types and sizes. We are novices and veterans of many years. We live in Massachusetts, Maine, Rhode Island, New Hampshire, Connecticut and Vermont (with a few members planted in other states and even other countries). We are apartment dwellers, suburbanites, country gardeners and commercial growers.

When irises are blooming in New England, from late April to July, ISM sponsors shows and tours of members’ gardens. We hold sales and auctions in the summer where modern hybrids are available at bargain prices. We publish a newsletter, and meet three or four times a year on weekends to discuss iris culture and gardening, to see slides of new varieties, old favorites, exotic species, and hybridizers’ seedling patches, and to hear from iris experts and enthusiasts from all over the country.

Newcomers are always welcome to join us for any event. Have a look at the schedule of events for more information or get in touch with one of our officers.

The Iris Society of Massachusetts is nonprofit affiliate of the American Iris Society (AIS) and AIS Region 1 (New England).
