The Dwarf Lake Iris, Iris lacustris, is a beardless rhizomatous iris (genus Iris, subgenus Limniris) native to the Great Lakes region of eastern North America.[1]

[edit] Distribution
The Dwarf lake iris is found on northern shores and smaller islands of Lake Michigan and Lake Huron, on the Door Peninsula of Wisconsin, and on the Bruce Peninsula and Manitoulin Island in Ontario, Canada.
Iris lacustris grows on alvar limestone barrens.[2]
Iris lacustris is a close relative to Iris cristata (Dwarf Crested Iris), the only other crested iris native to North America. However, unlike it, the Dwarf Lake Iris is found only in small areas of the Great Lakes region that have been glacier-free for only 11,000 years.[3]
[edit] Status
In 1998 the Dwarf lake iris was designated the state wildflower of Michigan,[4] where the vast majority of populations exist.[5]
Iris lacustris is designated a vulnerable threatened species by federal, state and provincial laws throughout its distribution range.[6]
