Updated 05/08/2013. Information is summarized from MNFI's database of rare species and community occurrences. Data may not reflect true distribution since much of the state has not been thoroughly surveyed.
The only plant entirely endemic to Michigan, this monkey-flower is found in cold calcareous springs, seeps, and streams through northern white-cedar as well as at the base of bluffs near the Great Lakes shoreline.
Natural Community Types
Northern white cedar, balsam fir, tag alder, marsh-marigold, watercress, impatiens, jewelweed, and forget-me-not.
This species requires maintenance of cold water source. Prevent disruptions to hydrology, including flow, oxygenation, turbidity.
General Survey Guidelines
Random meander search covers areas that appear likely to have rare taxa, based on habitat and the judgement of the investigator.
- Meander search
Survey Period: From third week of June to third week of August
Survey Comments: Often occurs with the non-native forget-me-not
