"Habitat and Ecology: The floating emergent vegetation P. attenuata also forms extensive beds in some reaches. This species is present along the river banks, but is not inundated at the end of the dry season, water levels having receded from the plants. Therefore, it is not possible to sample this emergent habitat in the late dry season – but it will likely be present in the wet season. Systems: Freshwater List of Habitats: 5, 5.1"

This is the largest smartweed species in Illinois. It can be distinguished from other smartweeds (Persicaria spp.) by the lack of bristles along the upper margins of its leaf sheaths (ocreae), and by its drooping cylindrical racemes with densely distributed flowers that are usually white. Other smartweeds have cylindrical racemes of flowers that are held more or less erect, or they have drooping racemes with sparsely distributed flowers. Pale Smartweed is similar in appearance to another large-sized smartweed, Pennsylvania Smartweed (Persicaria pennsylvanica) – however, this latter species has cylindrical racemes that are held more or less erect, and its flowers are often pink. Another difference between these two species is the size of their seeds
