Cold Climate Irises.

      I would suspect that Iris setosa (native to Alaska), Iris virginica,
Iris versicolor, and Iris pseudacorus would grow in your area.  There is a
possibility that Iris cristata would too.  I know that Iris tectorum is
being tried in New Hampshire, but it is a bit early to claim it will grow
there yet.
