Local in a heavily grazed pasture east of the highway. Occasional in wet silty muck along a groundwater seepage outflow, ~15 feet downslope from a calcareous fen perched on the gentle slope above. Scattered small clumps in moderately disturbed substrate settings; cattle and horses trample this area causing major erosion along the downslope margin of the fen. Full sun.
