In the News: The Dwarf Lake Iris – A Rare Plant Hiding in Plain Sight at The Ridges Sanctuary
Though abundant at The Ridges, only 165 populations are known worldwide. Research is revealing what this threatened plant needs to thrive.
Forming a veritable carpet of beautiful blue/purple flowers, the dwarf lake iris (Iris lacustris) announces the arrival of the summer season in a truly auspicious way. This federally and state- threatened plant is apparently quite happy in its home at The Ridges Sanctuary (TRS or The Ridges) in Baileys Harbor, Wisconsin. However, with the southernmost documented population in Wisconsin located only an hour’s drive away, there is a deepening concern that this iconic plant may be subjected to increasing environmental pressures, of which their response is unknown.
