Best Time for Blooms

Dahlias start to bloom in June and reach their peak of color in August and September, and will continue to bloom until frost. The garden attracts hundreds of visitors each year, including artists, photographers, and flower lovers of all ages. In addition to attracting a wide variety of insects and butterflies, you will witness migrating monarchs in September and October feeding on dahlias. You can find a shady spot to sit under the gazebo as you enjoy your visit. The garden has expanded to include additional beds for the 2018 season.

Dahlia Shows

The Long Island Dahlia Society hosts two dahlia shows each year in the Carriage House. The first show is held on Labor Day weekend and the second is held in October. See our calendar of event for more details. Dahlia growers from all over the east bring their blooms to display and compete amongst the top growers in the region. This is another excellent way to see the “best of best” dahlias on display.
