Ecological Context
White turtlehead is an obligate wetland species found along stream banks, in marshes, fens, sedge meadows, and swampy openings in floodplain forests. It thrives in circumneutral to slightly alkaline groundwater conditions and is an indicator species of fens. In the Outaouais, it occurs in moist depressions with Carex species and along lakeshores. Uncommon in both the Ottawa and Quebec-side floras.
