| Distribution | Mountains only. First collected in the 1890s by William Willard Ashe in Ashe County. Most recently, Wes Knapp found plants growing directly with Sagittaria fasciculata, and thus may be a threat to that population of rare plant.

| Abundance | Infrequent to locally fairly common; some populations may contain numerous plants, as at East Flat Rock Bog in 2023. | |
| Habitat | Fields, fencerows, yard weed, roadside waste places, public greenway, shallow water in montane bog. | |
| Phenology | Flowering and fruiting May-October. | |
