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.

Management
Protect habitat, maintain hydrology and natural disturbance regimes. This species most likely requires open conditions. Prevent woody plant encroachment by using prescribed fire or manual brush removal. Much of the appropriate habitat has been lost and degraded via conversion to agriculture, development, alterations of ground water hydrology (drains, etc) and fire suppression.
General Survey Guidelines
Random meander search covers areas that appear likely to have rare taxa, based on habitat and the judgement of the investigator.
Survey Methods
- Meander search
Survey Period: From fourth week of August to first week of October
Survey Comments: Best sought during morning hours when flowers are open
